Google Chrome is not lively says TechCrunch:

Here’s what they said:
First up is Google Analytics, which doesn’t track Chrome usage separately from Firefox (why Firefox?) for now, even though other services made the change immediately. Since Chrome is a two-year project and shouldn’t have been a surprise to anyone at Google, the cynic in me thinks they will wait until they have a few points of market share:

Q. Will I see Google Chrome listed as a browser in my Google Analytics reports?
A. Because Google Chrome was not launched externally until today, we haven’t yet changed Google Analytics to recognize it when you segment by browser within reports. However - this will change in the coming weeks (until then, the browser will show as Firefox). We’ll let you know when the change happens.
