Could G70 have more than 24 pipes?

Beyond3D is speculating that NVIDIA's new G70 graphics processor might have more fragment pipelines than the 24 available in the GeForce 7800 GTX.
The difference with G70 is that it is even larger than previous die sizes, which means that it is quite possible that full product yields may be quite small. Could it be that, in order to alleviate this, the defect rate is already built in to the current GeForce 7800 GTX and 24 fragment shaders is not the full number that G70 supports? Whilst many have speculated on an Ultra variant still to come and have been looking at the overclocks of the GTX’s to speculate where it may hit, perhaps it could be the case that there are 32 fragment pipelines in G70 and the fully working die are quietly being collected for use at a later date?
We've seen such things before, as in the vanilla GeForce 6800 and the Radeon X800 Pro. Sony is also doing something similar with its PlayStation 3-bound Cell processor, which will have one of its eight Synergistic Processing Elements (SPEs) disabled to improve yields.
