Don't know if this might happen,
but a recent change in the corporate profile of Vivendi Games (as given in their most recent press releases) lists:
''VU Games’ two principal studios are Blizzard Entertainment®, headquartered in Irvine, CA, the creator of World of Warcraft®, Diablo®, StarCraft®, and Warcraft®; and Sierra® Entertainment, headquartered in Los Angeles, which includes Radical Entertainment®, Swordfish Studios, High Moon Studios™, and Massive Entertainment®. Sierra is the owner of Crash Bandicoot®, Spyro The Dragon®, Empire Earth®, Leisure Suit Larry®, and Ground Control®''
Makes it sound like those Studios are what are beginning to comprise a new Sierra. Interesting that one of Sword Fish Studio's head honchos is Kelly Zmak, who was the head of Sierra at one time.
