They have done stuff like that before. 6 months is a long time in technology land. 16 GB would really be nice to put some video content on the thing and not having to constantly swap out movies. I have an 8 GB nano and I only have about 3 GB full and I put the unit on shuffle all the time, I hardly ever hear the same song in a listening session, so as far as music goes, I am fine with that, but movies can be over a gig a pop and pictures can add up very fast. My biggest fear other than they sell out is all they have left are the 4 GB models nobody wants.
