I hope this means a problem with GTA IV's multiplayer is resolved. I hated how there were no subway trains at all. I would have loved daring people to train tunnel races and see who makes it out. Same with using taxis and such. I remember in single player, I'd get into a cab, then pull out a grenade but not throw it. As long as I don't throw it, the guy keeps driving, and we both die. Made me smile. Those things they removed in the multiplayer really annoyed me, so it's good at least some of it is confirmed to carry over. I just hope it's more extensive.
