Apple never changes:
"Not Invented/Implemented Here" == Bad Idea
"Invented/Implemented Here" == Genius Idea
Larger iPhone was a bad idea at iPhone4S launch... now it's a brilliant idea with iPhone5.
NFC and Wireless charging are bad ideas with iPhone5... they'll be the hot thing for iPhone6.
Given the naming they've done over the years... iPhone6 probably won't be seen until 2014... in 2013 I expect we'll see the iPhone5S (ie the incremental improvement over the previous years phone design).
