Tried to play online. Took 3 mins to "connect" to a player then had a shitty laggy battle. Don't think I'll bother with online play since I have a wireless Wii.
Bebpo, like everyone has a wireless Wii. This game is not officially out yet...barely anyone is playing it online. It took forever for me to find matches, too, and they've been of varying quality. I had to set the search parameter to worldwide to even find any matches at all! Don't pass judgment on the online until the next few days pass and people in your surrounding area start playing.
Also still don't like the game. I didn't really notice the camera when playing the JP version, but playing this, something about the way the camera moves up and down spastically makes it hard to follow the action.
Are you super-jumping all day or something? That's what makes the camera move "spastically," and that's how these games have always been. There's nothing different about it.
And playing on a classic controller the game still feels like I'm struggling against the controls 90% of the time. Game is probably a decent fighter on a stick, but goddamn the GC or CC suck for fighting games.
Stick is obviously the most optimal way to play the game, but I'm not having any issues with the classic controller since it only uses four buttons. Maybe it's just been a while for you and your timing is off or something.
Also all the NEW characters added that I'd like to try "frank/zero" require finishing the game multiple times. I can't even be bothered to finish it once because fighting the cpu is zero fun whatsoever. So that kinda kills all interest in this "new" version.
I hate unlocking shit. HATE IT. But eh, you have to finish the game with three Capcom characters for Frank, six for Zero, and repeat the same process on the Tatsunoko side for Tekkaman Blade and Joe. Once you have all four of those characters, beat it with them (and if you used Frank and Blade towards getting Zero and Joe, I believe that counts as part of the process) and you get Yatterman #2. It's a little tedious, but the keywords are "a little." It's pretty easy to beat the game and you can always make it go faster by putting the handicap levels and super meter levels up and the turning the difficulty down, making it cakewalk. Or just wait a couple of days and see if someone puts up a save file to download.
The good thing about beating TvC's arcade mode is that you only need to finish the last boss with the character whose ending you want, so in other words, you could just have a team of Ryu and whoever, easily beat the shit out of the last boss by spamming fireballs and super fireballs, and then switch to your other character to get the last hit in, and it counts towards clearing the game with a new character.
Same old game that I never cared for much before.
Pass.
If you didn't care for it before, what makes you think you would have liked it now?

The orb boss is some bullshit too, haha.
He's pretty easy and just has a few nasty moves in each form that you can get the basics of avoiding pretty fast. You can obliterate him with any projectile users, but it can be trickier for those without them. If you just want to unlock shit, just stick with Ryu, Saki, Frank, Megaman, etc. and blast the shit out of him. Yami is far easier to beat than say, Seth in SF4.
Don't think I'll bother with online play since I have a wireless Wii.
As if there's any other type? 
You can get a wired adaptor for the Wii. The thing is, it might improve your connection quality, but what about your opponent's?

Everyone is going to play it wirelessly. Nobody knows how online play is going to be on the average yet since there's like five people playing online at a given time right now. I've seen reports of it being awesome and others saying it's god-awful. Nobody has any idea how far or how close everyone else is.
EDIT: I just had a couple of perfect matches. No noticeable lag whatsoever...so it can happen.
