Torrence Davis of The Bitbag writes, "Last night on the Warzone, Weapon X gave us the skinny on the GTAIV DLC. Here are the things he mentioned:
1. GTAIV DLC will arrive in late October or Early November
2. The DLC will be more like an expansion pack
3. It's rumored to cost 1600 MS points and will be very large
None of this is confirmed yet but Weapon X has some very good sources. Stay tuned for more info on this in the coming weeks."
