Microsoft will also announce the acquisition of privately held web analytics company DeepMetrix and plans to build new analytics capabilities into adCenter by expanding DeepMetrix's technology.

and from eWeek:

By incorporating the traffic intelligence features into its online array, Microsoft can better compete with Google. That's because Google recently introduced its own DeepMetrix-like feature, which it calls Google Analytics.

Microsoft's move reminds me of a quote I heard long, long ago (attributed to Rudyard Kipling, 1865 - 1936):

They copied all they could follow
but they couldn't copy my mind
so I left them sweating and stealing
a year and a half behind.

Come to think about it, it has been almost a year and a half since Google bought Urchin.
