The Wii's momentum is only going to decline from this point onwards, but if Nintendo plays their cards right, they can easily coast by on it for another year. They still have Skyward Sword, Vitality Sensor, Dragon Quest X (mostly for Japan), and a hell of a lot of games to localize for this year, and I'll bet they'll make a price cut at some point.
That said, the real trouble is going to start after the holidays, because as far as anyone knows, they have nothing to keep the momentum going for much longer, but at that point, they'll probably be gearing up for a new system launch, so they won't have to.
