At least, it's assumed it'll be identical: it's certainly possible it'll run slightly better on one console or the other.
I wouldn't be surprised if those downloadable content packs make their way to the Playstation Network eventually. It's also possible it could run better on the PS3 as well. I know I saw an article where one producer was saying getting it onto the 360 was more difficult due to the lack of disc space, and the fact that they can't count on users having a hard drive. At best I'd expect a hard drive install on the PS3 and something along the lines of better load times and less pop-up as a result though.
