Yeah, the subtitles went with Monolith to WB, but the trademark listings for both Spy and Jack are dead.
Right. There's a bit more to it than that; it's not as simple as "nobody knows." Stuff is happening, but not much.
I'd heard another story (this one apparently false) that it was Fox that retained the rights to NOLF because they wanted to make a movie, which may explain why some people think "nobody knows," but, like I said, apparently false.
System Shock 2's story was a biiiiit similar, except that EA ended up abandoning the trademark, so Star Insurance picked it up. Not sure how Night Dive wrangled the rights from Star, but it sounds like they're working together on it.
AvP2 isn't getting distributed, as far as I'm aware, because it's a similar situation to Wolfenstein 2009. That is, Activision owns the game (not sure how Bethesda managed to nab Quake IV; they're 'trying' to get Wolf 09, apparently), but they can't distribute, because they don't own the license. Basically, Sega would have to buy AvP2 from Activision, and it isn't worth it to them to do so.
