I was planning on replacing my iPhone this year as I have an iPhone 6. Currently I'm not having any problems with the 6 so it is not a case of outright failure that was making me look at upgrading. Usually I try to buy the best version of a phone available, figuring it will hold value and usefulness for the longest time. But this year that means a $1000.00 plus phone cost. I have read that Apple plans on having every phone in 2018 be an OLED phone, and that the manufacturing costs will also be going down. So potentially, a 2018 iPhone 9 will be significantly cheaper with one more year of new features than the iPhone 8 and the 9 could cost less money, or get a much more powerful phone/memory/features for the same cost. My iPhone 6 will still run IOS 11, and as I said, I'm not having any problems with it and usually there isn't that big of an improvement from one year to the next. But this time there are signs that there will be, especially in the cost department. I realize that A) its somewhat a matter of personal opinion when to upgrade and B) there is no guarantee that the 2018 phone will be any cheaper, and C) I may not be able to actually get an iPhone 8 this year because of supply, but I am interested in how others view this and if they would wait or buy?
