I figure the game's only about two weeks away, why not offer a preemptive tournament idea.
The rules would be pretty simple so most people can have an utter blast at it however there's always a few problem characters. in 4 it was kilik and it's possible ZWEI might be the same in the spam department, though that's yet to be seen. Two people I know will be an issue will be a custom character using the devil jin style, as in tekken games he's broken already. The second is Algol, which is more technecal and proven from the previous incarnation in 4 (official tournaments ban him for his unbalanced combo list and overall power to speed ratio)
otherwise maps would be fine, custom characters would be fine. If they allow a tag team style of 2 on 2 then that's a valid option. Mostly this is to sign in everyone who wants to be in so brackets can be made!
i'll be getting it day 1, juno probably is too, along with a number of others and i'm sure they can put away the 13-2 long enough to compete otherwise.
