If they’re only allowed to use wired controllers, why should they only be run on 360’s? Simply put, if you’re hosting a major tourney, allowing wireless controllers is stupid at this point, knowing all the issues.
If you really feel the need to allow wireless controllers, have a spare PS3 there that, when the player is done playing, you plug the controller into. That way, it’s synchronized with the spare system, and not the one being used for tournament play.
Having said all that… online petitions rarely work, but I do think it is a good option. Good luck with getting it done, regardless of the likelihood.
edit: in the event that you have a pad player, simply have two controllers tethered to the system at all times. Not a complicated solution to an over-exaggerated problem.
