Among other things that have come to light with THQ's recent Chapter 11 filing, four of the publisher's currently in development projects have been named. Or at least, codenamed. Whether it be codenames like Vigil's Darksiders II follow-up "Crawler", Relic Entertainment's not-Company of Heroes title "Atlas", or the actually trademarked titles 1666, from THQ Montreal, and Turtle Rock Studios' Evolve. None these projects are slated for pre-2014, but THQ is planning for the future and that's awesome.
I wish there was some solid evidence at hand to build some speculation off of, but it looks like THQ knew their stuff here and nothing has slipped through the cracks. Darksiders and Darksiders II's codenames were S.P.Y. and Tequila, so "Crawler" doesn't really tell us if Vigil has moved onto a new IP or not. Turtle Rock Studios last worked on Left 4 Dead 2 as part of Valve, but we do know Evolve is a co-op action game built on CryEngine 3. That's about all there is to know about any of the projects.
With THQ's tenuous financial situation, I wouldn't expect to hear much more on any of these titles in the near future. Doubling down on THQ's currently slated releases like South Park and Metro seems like the smart decision. Hopefully none of these projects are negatively affected and continue to be developed as per usual.
