And what about the industry-leading PS3? We already know MGS4 sold extremely well, but the same cannot be said (yet) for LittleBigPlanet and Resistance 2, both of which seemed to perform lower than expectations; LBP sold 611,000 copies in North America while R2 unloaded 600,000 units.
As for Nintendo, well ... it won. It always does. Last we heard, Nintendo stopped making games and was in the process of building a Kirby-shaped Death Star to orbit the planet.
