I seriously hope the iPhone is not offered in more than 2 colors; black & white.
When using my phone, I do not want to look like I'm using an iPod Touch, or want to see anyone else using it.
I would actually be up for only one color: Aluminum.
Modify the iPhone to a tear-drop, Macbook Air-esque form, that has a glass front panel similar to an iPad with edge to edge display real estate.
And no home button.
No need for more storage capacity, Apple is moving AWAY from local storage.
ie iCloud, iTunes Match, possible streaming service.
Don't we acknowledge that the future is moving towards ultra portable and light streaming/cloud based devices?
If Apple gets caught in a spec-based race against Samsung/others, and looses its creative take on devices we use everyday, then we can say goodbye to Apple in the coming years.
