The restructuring at Google shouldn't come as a surprise. Page made that clear when it was announced in January that he would be replacing .

The only surprise is how fast it happened.

Ezra Gottheil, an analyst with Technology Business Research, said the speed of this move is telling about how Page is going to run the show. "I think it answers the question about why Schmidt left," Gottheil said. "There was a divergence in vision. Page wants to move faster."

The first change in Google's management team came the same day that Page took over as CEO.

On Monday, Jonathan Rosenberg, Google's product chief, announced that he plans to resign. By all accounts,a pivotal player at Google, Rosenberg is expected to leave the company in the coming months. At this point, it's unclear who will replace him, or if he will be replaced at all.
