Wii comes with 1 remote and 1 nunchuck. In the U.S. extra remotes are $40 and extra nunchucks are $20. Out of the box anybody can play any single player game.
PS3 comes with neither until they announce their bundle prices. Don't know the prices for the extra controllers yet either. But for some games you'll need 2 Moves for 1 person (like the swordfighting or boxing), or 1 Move and 1 subcontroller for 1 person (like SOCOM). So if you want the ability to play all the games you might need to buy 2 more controllers.
Also, if you need a joystick (on the subchuck) you can't play 4 players. So you can't play 4 player local SOCOM, but a Wii could play 4 player local Red Steel in 2006 with all 4 players using the nunchuck. I think the lack of local multiplayer in those games will be a huuuuuuuuge disadvantage when it comes to the expanded audience, which is all about partying at home instead of playing online. But one-controller games can be 4 players, like bowling and ping pong.
Also, I don't think the PS3 can do Wii Fit or Natal. But now it can do some really interesting unique stuff like the EyePet. We'll see what happens. But no, the PS3 isn't now every console at once.
