The PS3 version will probably get the DLC in some capacity. Not too broken up about the Xbox version not having it on the disc. Bring Down the Sky is only a buck, and Pinnacle Station was pretty much panned across the board.

The DLC discrepancies could be due to memory issues. The Ultimate Edition of Dragon Age: Origins came with a second disc that contained the reams of DLC on it, and it had a pretty big install time. I suspect that they don't want to include two additional discs in the package that aren't really going to be used. There's also the fact that DA:O's edition was $60 bucks for the game plus all DLC, and this is $60 for three games and some DLC. They'd probably have raised the price if they included all of the DLC (well, all that exists at the moment) on it.
