I don't think there's going to be a pro or nano phone anytime soon. The current form factor is perfect for a phone, they might make a bigger tablet device but it won't be an 'iPhone'.
I hope they go back to the metal backed design, the first iPhone design was breathtaking the 3G iPhone a step back. Also the original iPhone matched better with Apple's current product line-up.
So besides a return to aluminium, I'm expecting a 5mp camera with video at decent resolution, front facing camera for iChat, beefier multi-core processor and more RAM (allowing flash, background apps, other new software features), and a bigggg software update for the first time changing and improving the fundamental UI as well as adding new features and apps.
I think some of the software updates will be passed onto the 1st gen and 3G iPhone, but others will be exclusive to the new iPhone.
