I have found some news on IGN about Pokemon Battle Revolution. It is a short preview but it gives quite a bit of info!
"Nintendo of America today announced that it has shipped Pokemon Battle Revolution for Wii. The E-rated title marks the first Pokemon game for Wii, but more importantly for some, it also happens to be the first project to make use of Nintendo Wi-Fi Connection for online play."
