One of the former Nival employees posted in his LJ about a staff reduction that took place in the company not so long ago. From his words, he (scriptwriter) and the whole design department were fired. The reason is "shortage of money".

"I dont know how they will finish second add-on with orcs, there is still a lot of work that needs to be done."

Also (and again from his words) the PR department was reduced just before them. More information (in Russian).
