I don't see how they could be anything else. Sure the English dialogue may well have been mixed for 5.1 from the start, but the music and sound effects are no doubt from the Japanese stereo masters.
I don't remember how R.O.D. was, but I know the 5.1 Japanese tracks on Gungrave and Champloo sound inferior to their stereo tracks, the biggest reason I haven't replaced them with the Blu-rays despite the very cheap price tag.
