I think it's pretty obvious how the system is supposed to handle game playback given that it has no cache (or very little) on the 512MB flash memory. Sure some of those games look nice, but none of them have as much going on as Black Ops, especially in multiplayer. Dead Space extraction is an on-rails shooter, so it loads what it needs to and then moves onto the next part. The Conduit mainly consists of corridors that look exactly the same (to decrease loading times I believe is how High Voltage explained that), Red Steel 1 isn't even in the same ballpark, Red Steel 2 is pretty laid back (from what I've seen, admittedly I've never played it). Twilight Princess is a direct port of a GameCube game, so obviously it's not as demanding as Black Ops and doesn't need to use any more resources than the GameCube version (besides what it takes to run the Wii controls). Super Mario Galaxy 1 and 2 both look fantastic, but again, they don't have nearly as much going on as Black Ops, and a lot of the loading is hidden when you fly to different parts of the levels. Metroid Prime 1 and 2, again, GameCube games, not nearly as taxing as Black Ops, Metroid Prime 3 probably started on the GameCube too.
