Yeah it was confirmed a while back, but I don't have a link. I'm not sure if they released the number of players, types of rounds, etc. A full-out 48 player tourny online would be pretty sweet.
That one mentions it, but no detail. Everyone kinda assumed it would be online because it'd be so easy to put online. Lag wouldn't be an issue because it's not a shooter or a fighters. It's a 'take-turns' game. Like cards or connect 4, lol.
