BioWare Trademarks New Eclipse Game Engine

GameSpot is reporting that BioWare has trademarked a new game engine called "Eclipse", although it is unclear which game will actually be using the engine. An excerpt from their newsbit:
Since Knights of the Old Republic and its sequel use the Odyssey engine and Neverwinter Nights uses the Aurora engine, it is unclear what game the Eclipse engine will power. One theory is that it is the final name for Jade Empire's "entirely new graphics engine." Another is that it's the "brand-new cutting-edge technology engine" at the heart of BioWare's original fantasy role-playing game Dragon Age. A third hypothesis is that the Eclipse engine will power both games, and a fourth is that it will be part of a new, unnamed title.
