I wouldn’t expect hardware updates, because they have only had a good 6 months with the iPhone 3G and the iPod Touch is even newer than that, but a new software update (with copy+paste) would be more than welcome!
I think software, yes. Maybe 16gb iPhone, no design changes. New iMac (No design changes or minor desin changes) Completely new Mac Mini Some, some upates on software, iLife maybe. Maybe some updates on the Mac Pro
