The "eventually everything will be massively parallel" argument is not very convincing. The Be guys made this argument 15 years ago and we're only now getting to where they were back then (2/4 processor cores). Consumers aren't that excited by more cores, and developers still don't know what to do with them. So there is massive investment in advancing the status quo. Sony thought they could impose the PS3's multiprocessing regime on game developers through market force. But developers found the programming overhead unmanageable, which led to a less-than-compelling lineup, which failed to interest consumers, which means that now developers just work on the Xbox 360 version and port to PS3. I was offered a job porting an existing game engine to the PS3 under the gun (the game had to ship in six months) and I would not touch it with a ten-foot pole.
