Well the 6s' price is gonna go down when the 7 gets out.
So even if you chose to go for the 6s, you should still wait till the 7 gets out. That said, you'll be able to make an easier choice when we actually know everything about the 7.
Oh and please, don't play PokemonGo
There will not be 7s!
There will be 2 versions - 7 and 7 pro
Depends on you. If you're ready to wait for a newer model - do so.
iPhone 6s if you ask me. No 3.5mm jack on iPhone7 is deal breaker for me.
Wait for the new iphone to come out and buy older one. Prices will be way lower
Why get iPhone when there is Android? (Don't get Samsung though)
