It may be possible to port the DDO game environment to a new game engine, which is a less extensive project than coding an entirely new game. A new sci-fi MMO called The Repopulation is moving its game engine to Unreal Engine after its original game engine, HeroEngine, experienced financial problems.

Turbine is a larger, more established company with more resources than Above and Beyond Technologies, so DDO may get a new engine at some point when its graphics are too dated to keep a sizable player base.
