It will plus the PS4 will probably ditch the Cell but will probably garner something as big since Multiplatforms on the PS3 usually are the worst versions.
Its all a IF and THEN. We just need to sit and wait. But a good indication that we are moving onwards is the 3Ds and the unannounced by CLEARLY there PSP2
I hope so

Still, one thing i hope for next generation is more cross platform stuff and the ability to use KB+M on all console games.
Also, it'd be feasible cryfan. Depending on the size of the psp2, one of the tiny low-end second generation fusions would easily thrash a 360 and would work in such a form factor. This generations 'zacate' APu's at least equal the xbox in graphics power, they just need more cpu grunt.
