The sites for both say PC/360/PS3. It's possible that they could be cross-gen, but Phantom looked weak visually, it could be a weak cross-gen release, but it sure didn't seem like it. I would put the odds higher at Dark Souls 2 getting a cross-gen release, but we really don't know anything except that PC/360/PS3 are confirmed.
To me it looks likely that there were no next-gen games shown, as none of them looked next-gen (can't judge Dark Souls either way because they only had a CG trailer). I thought as a whole the show was okay, but there really was nothing shown that couldn't be released tomorrow from a tech standpoint (at least that's how it appeared).
