DirectX games are hard to port to other systems, this game is meant to show off DirectX 10 and Windows Vista, so I don't expect a PS3 port.
Technically the PS3 should be more than capable of handling far more game compexity due to the cell processor. However this is only true if the game engine takes good advantage of the Cell's SPEs through multi-threading, using just the PPE the average performance is only about on par with a 1.6 Ghz G5 (a tiny percentage of the Cell's peak performance).
Testing indicates SPEs can achieve impressive efficiency rates (much more so than the XBox 360 CPU, at least it should be easier and its [x360 CPU) maximum peak performance is much lower as well) and are potentially very powerful for gaming and multimedia.
