Hi @Sonsuz, welcome to our forum and I'm glad to hear that you are interested in purchasing an Xperia XZ1. 
Your question has been translated to English as this is an International forum.
I'll try my best to answer your question, but keep in mind that I work globally so I might not be able to answer all questions regarding a specific market.
I had a look at the Turkish Sony Mobile website and the Xperia XZ1 is listed there, so it should be available, but you may want to take a look with the experts on your market, your Local support team! They are very well informed about market specific questions, such as launch dates, availability and so forth.
I hope that helps!
