Unfortunately, I don't think that going through the walls thing from them jumping is going to go away. From the gameplay videos, it looks like it's still there. It's also not about the connection.
I've played my own brother in the same house using 2 different Wii's and that stuff was still in the game. I think it's part of the game's engine, that's why lock-on kinda remedied it. There's always still hope though.
Tottentanz, although i do not agree with the fact your not very exicted for this game, i will applaud you for being one of the few people who list several valid reasons.
Hopefully, once the game comes out and if you get a chance to play it, maybe you'll change your mind. also, i will agree that removing online invasion was pretty stupd, but atleast they didn't remove it entirely.
i look forward to playing invasion with my brother in splitscreen and online of course and let's not forger the hopefully improved story mode.
