Excited to upgrade to the 7s! 
In all seriousness, wireless charging and good 3d facial scanning technology are kind of gimmicky at this point anyway, and there will be many growing pains even if they do pull it off for this cycle. These are exciting enough features that it's worth waiting at least a year for this tech to be perfected, on both the hardware and software sides. And as far as touch ID... I know I'm shouting into a well here, but if it ain't broke, don't fix it Apple!
