Its only 370kb on PS3 ( and unlock codes are around 140kb for PS3).

Im guessing that the verses mode is already on the is disk, capcom's code probably simply adds it the menu and allows access to it.

I don't think the versus mode is on the disc. However, all they're doing is probably add new multiplayer rules - a versus mode - which is as simple as writing some new code. Maybe they've also added an icon or two. Anyway, I'd say it's a bit too big to be on the disc already.

It should have been on the disc, that's for sure. It should have been free, even that would have been enough.

I don't even see it in the PSN store. Is it not available yet?

*EDIT*

It was on last night (04-09-2009).

i think it was i have the strategy guide and all the info and trophies for the DLC were in it
