It probably more to due with the PS3 issues, need of the new engine to handle server issues and PC side, and to be able to run on the PS3.

I hope to god, they do ntot hold back the PC version for because of the PS3 limitations, like the PS2 played a role in further progress of XI. Sure the PC was able to have better bump mapping and detail, but other aspects weere always limited to the PS2 ability to display items in variety.

Direct is standard. It is the most popular. Opengl is a rare thing in gaming, and lacks features. We don't expect the PS3 version to be amazing, jsut playable and smooth. Yet don't hold back the game on PC's becuase of the issues faced on the PS3.
