No one is going to know until they are in hand.

Well we do know that itms is going to be required as apple won't let you use anything else. There might be a hack of so sort but out of the box will require itms.

3 & 4 are sort of a combined thing. You'll need iTunes (not the iTunes Music Store or iTMS, though) to sync music/videos/photos up to it that you want to play or watch; you'll still (as current iPods) be able to use it as a USB storage disk just for storing files, though.

I can at least answer #4...it does support disk mode like past iPods:
