According to an official thread on TekkenCentral, the forthcoming Korean Tekken show "Tekken Busters" will be banning the use of solo characters. This means that in order to compete on the show, you must use the 2v2 format available in the game.
Furthermore, the use of the same character by different players on one team is prohibited. It has also been rumoured that Tekken legend, Nin will be commentating for the show. It has been fairly unanimous that solo characters are very overpowered in TTT2u. If this is true, I hope the rest of the world follows this rule set moving forward with the game.
