The press demonstration happened with a 360 controller because we were just in the process of implementing the PC interface. The presentation at Leipzig will be using the PC interface.

Sektor followed this up with a wikipedia link detailing the requirements for the MS 'Games for Windows' program. Deciding not to go for this program doesn't necessarily mean dropping controller support, so hopefully it will remain in regardless.
