I don’t know how big the memory chips are dimensionally, but the Fuze certainly would seem to be big enough to hold 32GB onboard, plus a slot. That would be pretty sweet, given that my collection is currently 32.7 GB, and 95.9% of that is lossy. I’m unsure about the Clip. I am inclined to think they’d be more likely to increase the Clips internal memory and not add a slot, so as to not cannibalize Fuze sales…but I could be entirely wrong too.
