KoKoRo, a Japanese blog, has a posting about what is apparently a very educated guess about the PS3's architecture. It's very hard to get good information about the PS3 or the CELL chip (1, 2), what with all the PR cloak and dagger warfare going on, but this analysis seems to confirm a rumour I heard that the PS3 will be even harder to develop for than the PS2 (which, as happened to the PS1, has been relegated to a small corner).

All the next-next-gen consoles will require some rethinking of development processes.
