have posted a preview of Conquest: Frontier Wars, Microsoft's upcoming space-based RTS which has been in development for 5 years! Heres a snippit:

    Exploring unknown space is always a risky proposition. In the Conquest universe, planetary systems are connected by wormholes. Jumping through a newly discovered wormhole is both an act of discovery and of faith; you can't tell if clear space or a hostile alien fleet awaits you on the other side. In the introductory movie, which features rather impressive cinematic CG (I-War's classic intro comes to mind), you witness the fate of the TNS Andromeda, sent out to investigate the Tau Ceti system.
