Awesome. Hate to see A:CM being pushed back (again!), but I was waiting for a new AvP for some time... Not too keen on Rebellion though, haven't produced a single classic in the last 10 years and even AvP 99 is flawed. Rather had Monolith if I had to choose from previous developers, but then again: both Lith and Rebellion prefer in-house engines, and both are lacking in mod-support. Other developers might have a shot too, but that depends on how well the new AvP does in sales...
Personal keywords: -Atmosphere -details -immersiveness -balance -STORY ARCH! (AvP 99 was a succesion of seperate levels and no motivation whatsoever, AvPII beat that by a mile) -Decent, preferebly class based MP experience instead of the tiresome DeathMatch...
