I don't think the graphics side of 3D means as much as the *gameplay* side. After playing Guild Wars I can safely say 3D RPGS have more combat depth: TO THE HIGH GROUNDS!
But alas, I like purdy pre-rendered backdrops. Unforfunately BD's arnt exceptionally amazing; nothing jaw-dropping in here like the good ol' days. The perspective feels really stale, as it did in DDiv, but that's a minor problem.
