If you're asking about specifics of the DLC plan they have, there's nothing about that that I can find. It does say on the official site that I linked that they have plans for post-launch content, so it could have more elaborate stuff even though it's not really mentioned anywhere.
Thanks for looking around too, Frisky. All I can come up with is foreign marketing materials. Ordered it from Amazon- had $39 in credit sitting there, and I've got a soft spot for Swery and Rising Star Games. Plus I really dug it on the 360, so I'll bite.
Breaking my rule about release day buying though :/
