It'll be really disappointing if the new sounds don't make it over to TSW2. I realize there may be technical hurdles, but for your flagship product to receive the inferior version just doesn't seem right. Audio mixing needs work across the board on TSW2, especially on Xbox- seems like now's as good a time as ever to bring it up to snuff.
The TS sounds are incorrect for the DB BR 187 anyways, however Skyhook is already getting the correct sounds from someone.
