I haven't heard anything but it wouldn't surprise me too much if they converted DTR2 to PS2, just the opposite of what they did with World of Outlaws 2002. WoO and DTR2 use pretty much the same graphics engine so it probably wouldn't be too much trouble to convert it to PS2 since they've already done all of the work with WoO.
the game is call "saturday night speedway" it has late models, midgets, and street stocks on 15 real oval tracks in the U.S along with figure 8s and 6 fantasy tracks. due in early as march 9th
