Infinity Ward's Robert Bowling jumped on his Twitter account earlier today, asking for help. Help with the design for a Modern Warfare 2 control pad.

The message reads:

In a design meeting for a #MW2 controller. Need your advice - Concave or Convex grips for the Analog sticks? Whats your preference and why?

Bowling later confirmed that this controller won't be coming from Activision or Infinity Ward, so it's most likely something similar to Mad Catz's Street Fighter IV pads, which seemed to go down pretty well.

Oh, and Robert: concave, please.
