While I think it will be fun, I feel like this is gonna be one of those games where people get good at it and then they start getting way too competitive with it. Especially if there's in-match voice chat, because then the community will just go to complete crap (yes, I'm envisioning this game like a TF2 type of thing). You'll have the veteran players commanding the noobs and then they won't listen and then a fight will break out..and since a game like this revolves around teamwork, it will effect the entire team.
Anyway, I won't be purchasing it early, but I may get it eventually. Probably on the eShop before I get it retail.
