There are lots of rumors circulating that Sony is working on a new model of the PlayStation 3. Supposedly this will be a "slim" model, similar to the last version of the PlayStation 2. There's also talk of features being added and removed. If they do make this new model, what would Sony need to do in order to get you to pick it up?
Personally, I'd want backwards compatibility with the PSOne and PS2. One of the rumors has it that this could happen because Sony just filed a patent regarding PS2 emulation. Perhaps they'll be using that in the new model.
