Further details on the fate of two of Sierra's four internal studios: Radical Entertainment and High Moon Studios. While new parent-company Activision Blizzard pledged to "realign staffing" at Radical and High Moon, it's been unclear what form this realignment would take.

Leah Rubin, Radical's vice-president of human resources, told Canada.com, "Activision Blizzard is committed to making the best games possible and has elected at this time to reduce the number of titles that Radical is developing from four games to two. Therefore, we will be proportionately reducing the size of our studio." The status at High Moon is less official, with "multiple independent" sources confirming to Gamasutra that "a notable portion – as many as 60 – but not a majority of the developer's more than 150 staff" has been laid off.

So, the sorta good news: Radical and High Moon will stay inside the Blizzavision family, as will Radical's two games remaining in active development and whatever High Moon has in production. By our best guesses, Radical's two games are Prototype and Crash: Mind over Mutant though we're not certain about the other two, now canceled, titles in development: One was rumored to be a multiplayer installment in the Jason Bourne franchise titled Treadstone and the other a sequel to the developer's 2006 Scarface title (the license recently reverted back to Universal). As for High Moon, with the loss of the Bourne license, it's possible that whatever title it's currently developing will be the fifth, unannounced title retained by Activision Blizzard.
