I imagine this will spark a whole 'nother bout of petty back-and-forth, but I have to ask it:
What makes you guys so sure there IS an ETA?
I realize that to work without a goal is pretty sloppy, but it's possible that the goal is simply "when it's ready enough," without specifying exactly when that will be. It's unsatisfying, yes, but I'm not sure it's safe even to assume that Lonnie has any arrival time estimation.
On a purely speculatory note, www.phoronix.com
has observed trends in the nVidia release cycles that call for a "major" release ~every six months, followed by a "minor" bugfix release about a month later.
For reference, 8762 was released 22 May 2006. I'll let you do the math.
