VMware Fusion 1.0 supports DirectX 8.1 graphics acceleration, there are no plans to increase this for GA as it is a Herculean task to virtualize a complete DirectX 9 video card.
We are seriously looking into improved 3D support as we plan future major product releases, but due to VMware policy to not discuss unannounced features and products, I cannot give you more details at this time.
Best,
