While at E3 (which admittedly I'm still recovering from) I was able to speak with someone from Digital Extremes, and I was told that despite their current focus on Unreal Championship for the Xbox (story) they have not abandoned Dark Sector, their planned massively multiplayer FPS. I was told that they were offered the chance to create an original Unreal title for the Xbox and jumped at it, and the changes they have made to the Unreal engine for Unreal Championship will be used for Dark Sector. Unfortunately when work will resume on Dark Sector is unknown, as Epic and Digital Extremes don't plan to sign-off on UC until the Xbox is broadband-ready, and at this point just when that will be is up in the air (there was a lot of confusion at the show as to whether or not the console will ship with any Internet connectivity at all).
