Nexus 7 Jelly Bean "nakasi"

Hello, I have a question i hope some of the Nexus 7 owners here can answers.

The other day I went to a store here in Denmark, to try the Nexus 7. I then checked the software build, and discovered that it was named "Nakasi". Is this the same as in the US, or is it a special european version, were the software updates are going to be delayed by months? Like on the Galaxy Nexus, where there is several different versions; yakju, takju, yakjuxw and so on.
