What Are Quick Man and Air Man Doing in Microsoft's Game Room?

Over on Kotaku, it's reported that a blogger found some interesting unused achievement graphics in the PC version of Microsoft's Game Room, a service that allows people to play and compete in classic game titles on the Xbox 360 and Windows PCs. So far Game Room has a modest collection of arcade, Intellivision and Atari 2600 games. However, could Mega Man be coming in a future update? One of the unused achievement graphics, shown right, appears to to have Quick Man, Air Man and Pac Man (one of these things is not like the other). Of course the unused graphic may be just that -- something that wasn't ever intended to be used. But it is curious nonetheless. News Credit: XD375
