The site itself now only redirects to bing. Last week you were able to find some info about the SciFi game from Brimstone interactive. (Still in cache)
The Facebook page for the mobile game was also removed:
www.facebook.com/EdenFallsGame (cached version)
Question is:
Is Microsoft now publishing the said SciFi RPG or will they revive Eden Falls by Lionhead and thus bought the domains and other stuff like the Facebook domain, Twitter Account etc...
My bet is on the latter simply because they removed all references to Brimstone on these accounts. E3 will hopefully give more insight.
