Now a few issues pop up with online:
1) would online lag, defeat the purpose of Wii motion plus
2) Would casual gamers actually play online, or would it take forever to find a game because so few people playing online
3) If a big number of casual gamers do go online, it could potentially be worse online than brawl
4) Wiisports is known for having fun with regular people around and having a sort of real life party, so online mode would be odd for such a game
5) How would Nintendo give a casual game a decent online gameplay that isn't confusing or hard to navigate and use ?
6) Wii Speak what about that thing? Would Nintendo allow smack talk for this game, Animal Crossing is about communication but this would only be for smack talk reasons and how would nintendo feel about it.
7) Wii Sports Resort will sell millions with or without online play, so is it even worth the trouble.
I would enjoy online play, and expect it but knowing Nintendo it will probably not even have 16x9 support
