Where?

When Hideyuki Furumi (EVP, Global Sales & Marketing, Sony Mobile Communications Inc.) in MWC 2018 presented Sony Xperia XZ2 and XZ2 Compact and siad speech (from 11:24 min., to 11:33 min) he was excited. He inadvertently confused the names of the models. There is no any XZ2 Premium model at this time official, this is just a mistake of speech
Thanks. Hopefully see it at IFA

Welcome, always is pleasure to help
I don't think that in IFA will be Premium mode of XZ2, but we'll see. If say true i don't care how called smartphone, to me important good device, good look and that's all. Name is just a name. XZ2 is premium smartphone too, just without "premium" word in name of model 
They are releasing another version though and it will be named pro or premium and it will have less bezels and dual cameras the the back, this was shown in the same presentation where they showed the xz2 and xz2 compact at the end they showed the dual cameras...nail in the coffin for the sale of xz2 when alot will wait for the other phone later this year

In presentation was showed only two models it's XZ2 and XZ2 Compact, there is no any Premium or Pro version at this moment. There is no any official information, how i know, about any Pro or Premium versions at all 
The first read post which other users posting before writing yours, was explained to Ninjabird7 about Premium model of XZ2, it was just mistake.
If you have official information about this models (Pro and Premium of XZ2), please post source link or stop post rumors 
if you want a source id suggest you watch their presentation video lol the source is all at the end when they show the dual camera tech on screen etc lol

I watched, there is no any Premium version of XZ2 official. If you saw Premium version in this presentation i advise you to watch it again, it was a mistake, as i wrote to Ninjabird7 
Hideyuki Furumi siad:
In 11 min:"Today we excited to introduce two new entertainment devices..."
In 11 min 20 sec:"They are...XZ Premium, XZ2 excuse me... I'm too excited. And Xperia XZ2 Compact..."
QUESTIONS FOR YOU: Where did you heard about XZ2 Premium in this presentation? Which from these TWO MODELS is XZ2 Premium? 
I added screen from presentation as proof that was presented only XZ2 and XZ2 Compact (look in presentation screen) 
Sony Mobile presentation in MWC 2018
I don't saying that will not be at all XZ2 Premium, but at these days there is no any official information about this model and was presented only XZ2 and XZ2 Compact. In end of presentation i did not heard about XZ2 Premium at all, so...
it showed off the back of a phone with dual cameras also look up and use google they cancelled the showing of the other phone due to last min changes to the design the phone has a 4k native resolution and which means it was the pro version

The first GSMArena is not official Sony web site, rumors always was and will be, second GSMArena wrote:"As some of you might remember, prior to MWC, there were numerous hints that Sony will release a total of three new flagships at the show. Obviously, that didn't come to pass and eager fans are still an Xperia XZ Pro or perhaps XZ2 Pro short.", this is example that Sony maybe changed it mind, that's can mean that XZ2 Pro will not be at all
As i mentioned a lot of time and you can't understand, there is no any official information about XZ2 Pro model at this time, how i know 
@KingSONYwrote:Premium model will coming soon with dual Camera :
XZ2 PRO can switch between single lens and dual lens mode...
This is not official source, rumors always was and will be, coz this is job of these posters, but there is no any official information about this model, as i know. Sometime in any test is showing specification of some models and later manufactor deciding to not release, so let's not mislead people here and let's wait. It can be and can't be, but at this moment there is no any official information as i siad 
UPDATED: After some posts about supposted model XZ2 Pro i started to look about this model a little bit more, so i found in one youtube (i guest) Japanese channel trailer of this model https://www.youtube.com/watch?v=dBwN_ylGCPs Keep in mind this is not official source, as i mentioned before, there is no any official information (how i know) about this model, yet. I mean that this model will release or released world wide. As GSMArena mentioned it can release later. But first mind which came to head after i found trailer of this model, it can be that this model will release only in Japan market at all. Coz in trailer almost all text is in Japan, when Sony releasing in world wide theirs models trailer coming only in english. So that's why can be that this model will see only Japan market or will not see any at all, but this is just my thoughts (opinion), i can be wrong, i don't know official information, which in english i did not found a lot about this model, just GSMArena, GismoChina (actually it's the same article which was posted in GSMArena), Pocket-Linit, Digit articles (there is some in others language, but if say honest all these articles are only rumors, there is no any official information about XZ2 Pro model yet, how i know)
In Sony Mobile Japan there is no XZ2 model at all in the list of devices which was released in Japan market http://www.sonymobile.co.jp/xperia/ 
Need to wait untill will be more information, even if will be official information at all about this model
