I found this to be interesting. Fount it on rpgcodex.
bitComposer filed for insolvency early this year, they are out of business. It seems, Bigmoon studios bought some 'Chaos Chronicles' assets from bitComposer before (I fear bC didn't inform Bigmoon about the legal dispute regarding the copyright).
And according to this trailer, the 3d engine (no lightmaps?) and the combat system are totally different to CC. I highly doubt latter is D&D 3.5e; looks more like D&D 5 to me.
