According to the Blood Knightsproduct page the release date has been postponed again, this time to May 17th. A post in developer Deck 13's forum explains what's going on:
The delays are caused by dtp's ongoing insolvency process. Deck 13 had to step in as co-publisher and take over certain duties they weren't exactly prepared for. Placing the game on all platforms was quite a challenge under these circumstances, but this problem has been solved. It's still unclear though when they'll get release clearance by the platform holders.
Deck 13's action RPG with co-op multi-player is 99.9% finished.
Thanks, Couchpotato and GBase.ch. More information.
Couldn't quite work out if you get to play with two characters like (a more action oriented) Beyond Divinity or whether that's just a coop multiplayer mode. Having a companion would certainly make the game more interesting to me than another straight ARPG and there is a suggestion that you can switch between controlling the 2 characters.
