I've been thinking a lot about this and after John Gruber and Jim Dalrymple have essentially "confirmed" that an iPhone and iPad mini event will actually be two events, I got to thinking about the next iPods, specifically the Nano.
I gotta think they're working on a much smarter device. A device that will communicate a lot more with iPhones and iPads. Bluetooth 4.0 would be key, and probably a bigger battery, too.
What do you guys think?
