So bit late to the news, but recently Crytek (the guys behind Far Cry, Crysis, and the CryEngine) has stated that they intend to bid on the Darksiders IP at the THQ auction in April. Dunno if Platinum Games is also going to be there.
Overall always glad to see that the series will hopefully live on. While not what I would call a AAA uber-awesome amazing series, it's still one I'd hate to see perish amidst THQ's demise.
