I know that there won't be any DLC, it's been confirmed in interviews already, which I found surprising, but only because they admitted flat out that there wouldn't be any when asked about it rather then trying to dodge it.Ugh! Just great. You don't think there will be downloadable content for the game? New characters? Fights? Stages? Modes? Darn.
Also note that Burst Limit isn't the first next gen fighting game, ie Dead or Alive 4 and Virtua Fighter 5 and Tekken: Dark Ressurection have all come out on either the PS3 or 360, and none of them had DLC. Soul Calibur IV won't have any DLC either aside from what's already on the disc.
Fighting games seem like a natural source for DLC however the truth of the matter is that they never have DLC for multiple reasons. For instance let's they made Zarbon, Dodoria, Coola, Garlic.Jr, etc, as DLC and they released each one monthly, well it make playing online really difficult because whoever your playing would have to have all the exact same DLC you have and if everything (characters, stages, costumes) were released seperately it be problematic for the online mode. Now of course they could make a single expansion pack to make it easier, but they'd rather save that content for a sequel as they don't get a lot of time to develop sequels and it would just limit what new stuff they could have in BL2 if they were releasing DLC.
The other thing people have to realize about DLC is that at most you usually only have around 30% of people that bought the game buying the DLC, and given that DLC doesn't make very much (or any) profit along with the time having to spend on something that most people aren't going to experience, ontop of the fact that first parties like Sony and 360 get a cut of the DLC profit most developers don't want to do DLC.
DLC has lots of potential for what can be done with games, however it's not very viable, thus you don't see many companies doing it, or when they do something it's not all that major.
