Searched but didn't see a thread on it. VGLeaks has some info on a kinect RTS epic is (was?) making:

There are more screens at the link. They're (bad) captures from a video as article states
edit: per some of the comments below, this project was mercifully canned
Kinect has changed the Microsoft policy. They have changed the hardcore games for Kinect games. RARE abandoned IPs like Banjo, Killer Instinct for casual games. Only Halo, Forza and Gears of War stay with us.
Epic hinted a Gears of War only for Kinect. This game is called Gears of War: Tactics (temptative title). A RTS based on GoW franchise. We would like to show you pictures of this game, those pictures are extracted from a previous footage. The graphics are poor, obviously, the video showed a game in works, probably an alpha version, maybe more primitive.
In Tactics you can take the control of four players. Draw a path with your finger until the place you want to move the character and later you choose an action (or make and action and move later, like you want). One by one or groups, you have the control.
Epic Games were developing the game for Xbox 360, but now probably they moved the project to Durango.

Cliffy - "Let's just bury the hatchet now, Gears of War: Exile was an unannounced game that I can't give any details about that has since been cancelled."
Unless Epic were working on two Gears games for Kinect, which seems unlikely, we can assume this is the same cancelled project.
