I, and many other people don't want a bigger phone. I have a 7" tablet. I don't need a 5" freaking phone in my pocket. Or the monstrosity that is the Note. Might be alright for girls with handbags but no good in a pair of jeans / suit pocket.
the myth that more megapixels produces better pictures is nuts. some of the 12mp cameras are awful. It' more about the WAY the CCD captures, the compresssion used and even more about the Lens used. In fact the only way to dramatically increase quality is to use a big lens like the Pureview Nokias or normal compact camera.
And unless I can control the captured image size/res I don't want anything bigger than a 8mp. that's 3456 x 2304 - more than enough to print on A4! 12mp is 2x the storage space.
As for the colour. it won't look like those horrible renderings it will be a lot more subtle like the 'spare parts' - not that I would buy one. I love the black but took it back as it needed to be kept in a case to stop any damage... And why would you want to make your phone bigger!
I'm not saying that EVERYONE wants or needs a larger iphone. But you can't ignore that that is where the majority of the public is trending lately. It's just a fact. And one that Apple can't ignore. I am sure they will come out with a larger iphone eventually. They always do this. Say they'll never come out with a tablet...then they do. Then that there is no need for a smaller ipad...then they come out with an ipad mini. Same with the iphone. Mark my words, they WILL come out with a larger iphone. I'm not saying it'll replace the current size...but rather be sold alongside it.
