Wow. It shouldn't be a surprise, but wow.
Someone said a while ago we're hitting a point of diminishing returns when it comes to hardware improvements to market new systems; its simply getting too expensive and financially risky to make games that take full advantage of the power this generation. I want to know how many of those new games were originally slated for the PS3 and 360, and will now show up on the Wii in a less-pretty form. I've joked/scorned the fact that many games out there could've been done on the previous generation's hardware from a gameplay standpoint; I think this might be a validation of that.
I'd like to think we'll see more titles making use of the SNES controller - it makes sense. Certainly more sense than attempting to shoe-horn everything into a Wii-mote control scheme. Given the relatively low cost of the SNES inspired controller ($20), I think this is a good move for more traditional games provided they put a prominant display of that requirement on the game box.
