Honestly, I couldn't agree with you more. The fact of the matter is the animation is still a little bit iffy and I have seen some copied movesets. As for ZSS she has the C. Falcon kick it looks like just a little bit faster and without flames or darkness (Ganondorf).
I would rather have a delayed online version rather than the sooner plain multiplayer version for a number of reasons. The only way to get better is to play with better people. So I am really looking forward to the game's release whenever it is ready.
Edit: Also if you look on bestbuy.com, which you can pre-order from now. It says that the release is going to be on 3/15. Same date they say as Galaxy. Honestly I doubt this.
