Kudos to Merkinjata, who passed along an interesting bit of information from a somewhat recent PR from Turbine Software. To whit:

...David Bowman joins Turbine from Bungie Software as Design Director, and Kemal Amarasingham joins from Looking Glass Studios as Lead Sound Designer.

David Bowman joins Turbine from Bungie Software, where he designed for their hit series Myth ( One of the Best Games of All Time! according to PC Gamer) and Fantasy Siege, the forthcoming hit based on Bungie's Halo engine. According to David, Turbine is doing the most exciting work in the massively multiplayer gaming area. I'm excited to be a part of such an excellent team.

Odd that Turbine waited so long to announce this, as this has apparently been in effect for quite a while. It's also interesting to note that the Fantasy Siege title has popped up again... working title or production title, only taste will tell. ;)
