I find it highly unlikely- dare I say impossible- that the 6 will have an A7. Itll be A8 for both and the "6c" (if thats what its called) or "5S" will be the A7- todays specs. If I were to guess I'd guess we'd see a 4.7 6, a 5.5 6, a 4 5S (99), and a 4 5C (free). Not sure why they'd change it up this year since thats how its been for years. The 'free' iPhone will likely have the A6 as well- which, according to the past, would be the 5c.
