How else would they achieve such a radical jump in texture resolution
Unless they use procedural synthesized textures, a crucial bottleneck is storage capacity. Forza 3 uses 2 DL DVDs instead of 1 DVD for Forza 2. So this suggests they either use higher quality textures, or supply more of a texture varierty or a combination of both.
Considering the PR statement it's likely the textures used for Forza 3 take up more storage space (higher quality textures).
