I think we might see a couple more 10+ Million selling games on a single platform this generation, but the only game I think is a "shoe-in" is Wii Sports: Resort (which is developed by Nintendo) ...
It is very difficult to achieve sales of this level because (between rentals, piracy and used game sales) you need an amazingly high percentage of users to buy a game to get to that level ... Most games that achieved sales of this level were bundled, although there are a few that have passed 10 Million without needing the help of a bundle.
