I thought he was referring to double-precision on Nvidia gpus,
which have indeed not been shipped publicly (afaik).
An article posted today about the GTX280, which is to be release tomorrow,
states that the GTX280 has "support for the IEEE-754R double-precision
floating-point standard."

So a very reasonable question to ask is what the latency is from the
stream processors to the device RAM.
sure, they're GPUs, not general-purpose coprocessors. but both AMD and
Intel are making noises about changing this. AMD seems to be moving GPU
units on-chip, where they would presumably share L3, cache coherency,
etc. Intel's Larrabee approach seems to be to add wider vector units to
normal x86 cores (and more of them). I personally think the latter is
much more promising from an HPC perspective. but then again, both AMD
and Nvidia have major cred on the line - they have to deliver competitive
levels of the traditional GPU programming model.
