This will help people who may acquire the game just to participate regularly, in knowing what to get it on. Catering to everyone's specific needs is just not possible, there will always be someone with the oddball game for another system than the others, and we will just do our best to cater to as many as possible.
If we wanna add a default system or 'dedicated' system to stick to and always pursue as a 1st option (granted the games chose are on that system to begin with)... I'd probably suggest PS3 for a number of reasons- PSN is free unlike XBL, it has long been the 'tournament standard' for many fighting games and PS3 accepts a good many more out of the box peripherals than the other consoles (except perhaps PC).
But if someone else has a counter to that opinion, I am completely open to discussion for any and all of it. Which is why we need to iron a lot of this format out before we jump into it

Come at me bros
