THQ has promised to "fully unveil" the new Warhammer 40K MMO at this summer's E3 2010.
Boss Brian Farrell told investors this IP could run for several years, and therefore represents the "highest ranking revenue opportunity" the publisher has.
Farrell added that in Warhammer 40K, THQ has a "very competitive MMO".
So far we know little about the game. Darksiders' Vigil Games will develop under the creative lead of Joe Madureira - presumably alongside the Darksiders sequel due out before April next year.
Madureira's said combat will take place on a larger scale than Mythic's Warhammer Online and that there will be "tons" of customisation and the "coolest looking characters of any MMO, ever".
E3 takes place on 15th-17th June 2010. We'll be there.
