No chatter on this thus far 'round these parts, but I for one am very excited to get my hands on this. I have been trying not to read/watch a lot of the preview stuff, but the multiplayer aspect looks like a BLAST.
I remember trying GTAIV multiplayer with Jackie, Ebil, and one or two other people, and for that short period of time, it was awesome. Not sure we ever actually left the dock area where we started, as we started crashing cars into each other, scrambling for/crashing the nearby helicopter, and racing for the rocket launcher on the roof.
Anyone else looking to dive into this?
