I'm also really hoping that Apple will release a 64 gig iPod Touch.
The 1st generation Touch was originally released in Sept '07 with both 8 and 16 gig models, then the 32 gig model was released 5 months later in the beginning of Feb '08.
I've held off (its been a struggle) of buying a 2nd generation Touch with the hope that, like last year, the capacity will be doubled after the holidays, perhaps after MacWorld '09.
I've got my fingers crossed.
