I wouldn't see why not. If they needed to, just reduce resolution overall to support more controllers, given how much lower than actual HD (720p) gamers have been willing to put up with this gen from top-selling games on the HD consoles, certainly similarly low levels could be tolerated as an exchange for multiplayer
My guess is the second controller will be sold only with extra software, something that makes use of it, like Wii Play was this time, as it will be a more premium product than a mere standalone accessory
