seriously, this is the place to go for every MvC3 info you need. Just click on the character potrait and it gives you everything you need to know, including some really cool video walkthroughs. Amazing job from the dudes at SRK.
 
MvC3 SRK Wiki

Thanks for the link! I'll check it out.

Looks pretty good. Nice layout, easy to navigate and video guides are always a plus for me ;)

Awesome. Wish it was just released now. Absolutely desperate to play it...

the video walkthroughs are so good, discovering a bunch of moves i didnt even know the characters had, or how to do some moves...Modok's aegis shields are just back+heavy? damn!

Oh man this is Awsome. always nice learning some combo's for ur characters

WHAT THE FUUUUUUUUUUCK? VEGAS HAS IT? WE BOTH LIVE IN CARDIFF. WTFFFFFFFFFFFFFFFFF

Thanks for the link, though it's more fun to figure things out as a community ;) 
 
Also, Super-canceling Thor's Mighty Speech? That's going to be a perfect crowd pleaser!

Radical!

Thank God! The command lists in the game kinda suck.

SRK got a major overhaul once again! This time much better.

I was just coming here to post this, this looks great for beginners.

I think its pretty helpful that it shows the amount of damage a move does.
 
And on a related note, I sure do love me some wikis

The SRK wiki... let's just say this is more than I was expecting. Well done to all involved.

Awesome wiki, the video playthroughs are pretty damn good.
