Dubbed Pokemon Battle Revolution, it looks like tag-team battle is the emphasis this time around. Also, the game is to be able to utilize the upcoming Pokemon Diamond and Pearl versions to exchange correspondence via Wi-Fi and swap pokemon, along with displaying the 2D battles of the DS game on your TV in 3D through the Wii. Other features are mentioned, but using online translation tools doesn't give the most accurate descriptions, so in fear of reporting something false, we'll just leave the post at that.
[Thanks nushio!]
