Super Smash Bros. for Wii U has gotten a new patch which allows for 8-players to play on 9 more stages:
Mario Circuit (X)
Luigi's Mansion
Pyrosphere
Norfair
Lylat Cruise
Pokémon Stadium 2
Town and City
Smashville
Wii Fit Studio
Wow, I wasn't expecting this I have to say! This is great, it annoyed me you could never play on all of the stages with 8 players. I probably will only try it out on these stages and then never play again because I don't play 8-player Smash. But I still like that they've added this functionality.
