It's sad, the purest Google experience doesn't even have the OS... I would say you can ask "Where the hell is it?!" after the Nexus One gets it, but as of now... kind of not important.
Actually word is that 2.4 is coming instead of 2.3, 2.4 is Gingerbread with bug fixes and maybe(rumours...) even dual core support,
As of now, the only device with Gingerbread is the Nexus S.
Honestly though, Gingerbread on the Nexus S is pretty bad, pretty unstable... I am glad manufacturers haven't updated any devices yet, because it's just so unstable. That's why I have CM7 on my Nexus S, fixed the launcher freezing up and the 1.2ghz kernel makes it get 2000s on Quadrant, and even eliminates the browser lag.
