Larrabee: No Support for DirectX!?

According to the last rumors from the web, Intel does not plan to provide hardware-based support for the Microsoft 3D API set, aka DirectX with Larrabee. If we do not know how the company will program this video chips to speed 3D rendering computing, it seems it will be different way than with this popular API set.
Of course, it would be excellent news for Mac users, as the main break for developing or porting games on Mac is the proprietary DirectX API set, which is not available for Mac OS X. If Intel defines a new way, and considering that the honey moon with Apple still continues, the Mac could regain some appeal for 3D games.
