"The new Motorola starts today." That was new CEO Dennis Woodside's proclamation during the unveiling of the new RAZRs, and I think that statement gives away a little more than intended. Smartphone development takes the good part of a year, so they're implicitly admitting that these phones were made by someone else. That "someone else" being the old Motorola.
Yes, Google's deal to buy Motorola was announced a little over a year ago, but, thanks to all the regulatory bodies around the world that had to approve the deal, Google has only been in charge of Motorola for about three months.
