nVidia pushes out 2+ beta drivers a month. Usually they only have one alpha release a month. They're on par with ATI; only difference is that ATI doesn't release beta drivers left and right like nVidia does - instead, they rely heavily on feedback crews, and consumer feedback (us) for driver development. If there's an issue they're trying to resolve, we typically see either a hotfix or a beta release.
Now, if we start calling beta drivers as "official" driver releases - than yeah, I'll defi admit that nVidia releases more drivers than ATI does.
And saying that ATI is lucky to see monthly driver releases anymore is absolutely ridiculous - and you know that, man - ATI has been following the same 1 official driver release per month schedule since, what? 2004/2005? We all know round about when the next driver is rolling out, there's no guessing or hoping involved. If there was any evidence that ATI would start cutting back to quarterly or bi-monthly driver releases, we would've seen or heard evidence of that already.
I understand there's a debate going on, but in the heat of a debate one's comments can start coming across to be very fanboish - not calling you a fanboi, newtekie1, but IMO, that quote on the driver releases very much sounded that way.
