This is primarily because of the significant drop off in performance of texturing via PCI-e. Attained on demand texturing performance over PCI-E has historically been beyond horrid with real world bandwidth in the low single digits.
Vendors are making changes to their hardware/software stacks for PCI-E data to increase performance significantly, primarily driven by the HPC markets. While this may not make PCI-E texturing viable for games, the next gen consoles and their associated memory architectures might make ultra large texture games more common place and therefore provide a quality advantage to a GT3e like design.
