Assuming the Full iPod AV comes true...
... would you buy one? I've looked at this picture (other sites have taken them now by now, I guess I'll have to take this one down, soon, too...) for a while, and I must say, I'm intrigued. Whether the "leaked images" are fakes or the real thing: It's the logical evolution for the iPod with video, because a "real" clickwheel, even if further reduced in size, simply takes too much space on an iPod to allow a bigger screen, and a bigger – and more importantly *wide* – screen is certainly the next step that Apple has to take if it wants the iPod video to succeed in the long run.
I've told myself back when Apple introduced the iPod that I would buy every second generation – unless the feature-set would not be enough to convince me to change. So far, I've had the 2G iPod 10 GB and the 4G iPod 40 GB. I think a 6G iPod 80 GB sounds like what I'd be getting, if the images prove true.
Do I really want to watch videos on such a small screen? Heck: Yeah, I do. I've got my home cinema set up, and certainly many movies are not made for such a small screen, but many things are just fine on them. Video podcasts, animated shorts, they all work fine on a 5G iPod – and would work even better on a larger screen. The thing to tackle, for Apple, is battery life, really. While the 5G iPods do just fine with music, they don't really shine with video so far.
