Considering my bad eyesight severely limits 3-D for me (9 times out of 10 it simply looks 2D), so I'm hesitant.
They're really pushing 3rd party, which was definitely the biggest question mark going in; at least they acknowledging it. If those games (Metal Gear, Kingdom Hearts, Resident Evil) can actually pull it off, even on just their handheld, it'd quiet a lot of worries.
