<< Meanwhile nVidia's formerly extremely strong mainstream positioning for $500-1000 cards was doing very well indeed but has been quickly falling on hard times without Elsa to back them up, and they've been entirely unable to even approach ISV certification standards in their drivers without Elsa's expertise in that area.

You are very mistaken. Nvidia was formed from Sun/SGI spin-off, and they have one of the most talented engineers and driver writers. Elsa drivers are practically based on Nvidia reference drivers, with couple of "plugins" to increase performance in 3d studio max and other applications. Due to extremely good relationship between Elsa and Nvidia, I suspect most of their people will join Nvidia if Elsa will fold. In fact, I am sure many already did.
And can throw some opinion of Carmack on this issue.
<< We bought three generations of intergraph/intense3D products, but the last generation (initial wildcat) was a mistake. We use nvidia boards for both professional work and gaming now >>
<< Nvidia's OpenGL drivers are my "gold standard", and it has been quite a while
since I have had to report a problem to them, and even their brand new
extensions work as documented the first time I try them. When I have a
problem on an Nvidia, I assume that it is my fault. With anyone else's
drivers, I assume it is their fault. This has turned out correct almost all
the time. I have heard more anecdotal reports of instability on some systems
with Nivida drivers recently, but I track stability separately from
correctness, because it can be influenced by so many outside factors. >>
ISV certification is not an issue. Quadro brand is very strong, and will only get stronger with Quadro 4 release. They have cards for every segment of the market - dual and quad monitors, low, mid, and high end.
