Twisted Metal was Sony's big announcement at E3, after they claimed repeatedly that it wouldn't be shown. However, they also showed off 3D and PlayStation Move heavily at E3 and Twisted Metal will feature neither of these technologies.
Speaking on Twitter, Jaffe said "3D has to be 60 frames and we are not. We are gonna be rock solid stable but not 60." On the note of PlayStation Move, he added "Move and Twisted don't seem a great fit."
So there we have it - Twisted Metal will be featuring neither of Sony's premium technologies.
