The demo has finally arrived, pulling it down at the min. Been following this for a while now as I love his books and thought Undying was literally one that passed many by. Jericho looks extremely creepy and the engine is inhouse design, hopefully it will run better than Unreal Engine 3 on the PC!
Few different mirrors for it at the min but Fileplanet is still yet to get it. Fastest one I found is here :

Just a quick warning though, you must have a Shader Model 3 card to be able to run this one! I will not give in to requests for laundry bills either for soiled underwear!
