The HDDVD thing sucks and I hope it doesn't turn out true... But then it IS inferior to Bluray so it's going to become the standard (Law of Inverse Darwinism: The worst technology always becomes the standard, see x86, PS2, Windows, Gameboy, VHS, etc). And having the standard is always nice.
The two-processor stuff sounds like they're going to use those PPC970-thingies, which seem much better than those Cells to me. Less performance maybe but you can probably develop a game three times as fast on it and have significantly less bugs in the final version. I've read an article that interprets the Cell patent and what I read there sounded like a nightmare for any developer (no abstraction on a massively-multiprocessor system sounds like bugbait number one).
