Reggie Fils-Aime has revealed the full details of when the Wii will be playable online. In a recent interview with SpikeTV he had this to say.

The multiplayer is coming. During the Japanese launch, there is Pokémon Battle Revolution, and that’s really the first one. There will be titles that we’ll be announcing in first quarter 2007, that’ll be multiplayer-enabled. So during second quarter 2007, people will be able to have a multiplayer experience on Wii.
