It'll be interesting to see how the first 4 player game works. Presumably there will be something like doubles tennis or table tennis, maybe 4 player DDR or something along those lines.
Naturally there will be the obligatory 4 player party collections of mini games as well.
If the camera itself uses a motor to track a moving player (not limb movements, but lateral movement) there may be some limitations as to how it can track multiple players at once. Of course, there will always be the physical limitations of room size, and any in-game requirements for faster or more exaggerated actions. You can't exactly have four players running around a 25' square playing field.
