My thoughts...
Apple will not release a new iPhone until next june. They will argue 'till their blue in the face but they won't release another one early because of how many people are still buying them.
As for the iPad, i think a smaller screen is coming, but not yet, probably around early april next year, a year after the original. I definatley think it will have face time and a front camera too.
I think the new iPod touch will have a retina display, A4 CPU, front and back camera and facetime. I also think augmented reality games for the iPod touch will take off when this is released.
I think the iPod nano may be the device with the rumoured 3" touch screen and the shuffle will not be updated. The classic will go.
And i hope apple release a bumper that covers the back of the phone too
Just my thoughts on what seems logical to me
