Game Templates In UE4

I would love to get a few things dedicated to Oculus Rift.
And what works best in VR is cockpit games: I know that a flying template is on its way, but what about a small car/race game, where the Oculus Rift would no turn the car but allow to look freely around

Do you have an ETA for opening the marketplace?

EDIT: oh, and an example of a 3D menu is a must have!
