Please use this thread to discuss everything about iPhone 6 Games. Apple will be released iPhone 6 this summer, so I think some developers like Gameloft will be the first to make their games to support iPhone 6.
Iphone 6 is yet to be announced and one of its specifications are avialable in the mobile market, So, I don't think that Developers would be making games for the upcoming Iphone 6. We will have to wait for that.
