I really hope this isn't also for 360. I was kind of hoping it would be made from the ground up on PS3.
Why?
The GPUs are similar in featureset and close in performance (Xenos may even be better).
In terms of FLOPs, Xbox 360 is theoretically only 50% as powerful, but makes up for that in other areas. Worse case they would have to cut down particles, physics, etc... in half. Either sampling or number... so instead of 10,000 physics bodies, say only 5,000 (of course other bottlenecks and such could bring those numbers closer... or further...)
Anyhow cross platforming does mean less exploitation, but graphically the 360 is not far behind (if at all). And if they even plan to use the SPEs much it will need a rewrite and/or codevelopment anyhow.
I guess down the road I see a lot of devs co-developing engines... a core set of features on the PPE elements, and then FP type tasks that are either SPE friendly or PPE friendly, and then tweaking from there.
I guess I don't see it as a big deal... from a market perspective going cross platform is good $ wise--so if you want them to float then this is not bad
And from a market position, with the 360 out earlier and with more games it would seem it makes sense.
Oh well, I guess next we will have an Xbox fan upset it is not an Xbox exclusive because they were hoping it would exploit the 360
