Not at all, and as I said, motion control is exploding with potential, particularly with (arcade) shooters. Somewhat similarly, I've also wondered why light gun-type peripherals never really took off on home console. Perhaps current-gen motion control can take up something like that?
People slag off the Wii, but some games over there are doing interesting things with motion control - like Metroid Prime 3: Corruption, Resident Evil 4, and Sin & Punishment (I've not played Red Steel 2 yet - it's unopened on my desk, heh - but I'm expecting something cool). Hopefully MS and Sony can move from this, and take it into HD.
