Im still waiting for speed racers and battleship mode. There are stats for the sparrows, even though the only stat is speed and vulnerability. As for the ships, we have guns on them. Still waiting to actually fly around with my ship and not use it as a loading screen. I dont see the point in wave mode. We already have that in story missions, strikes and public events. Most likely we are just going to find some way to exploit it for XP, which is what I will do if it ever becomes a reality.
