It would be in Apple's best interests to introduce something like that. Thats one of the main reasons I like the iRiver line and many other products because they have a much larger screen.
The only concern that I would have is I hope they would release a stylus so the screen wouldn't be so smudgy. BUT, I'd also be afraid that a replacement stylus would be a lot of $$$ lol. Maybe they could put one of those "loop things" on it like digital cameras have so you could attach the stylus.
Nice looking mockups though, thankfully they're a little choppy so people won't say THATS THE NEW iPod with Video (hopefully).
Kinda check out these mock up pics on someone Blog spot..
If it dropps like this, im picking one up..
