The most complete preview to date has been posted over at zdnet: Gamespot and it reviews what we've pretty much mined out already but they do have most of the neat character sketches and game details. Here's an excerpt:
"Although, we are taking a [new]route in terms of adding 3D acceleration, 3D models, and doing stuff with the terrain engine and physics that are still way beyond what the other RTS games are doing right now." However, the game will still use much of the underlying technology from Myth II: Soulblighter. This lets the designers at Mumbo Jumbo keep the core gameplay from the game's predecessors but gives them room to add lots of new bells and whistles to keep the series on the cutting edge.
