This company makes a lot of money, they still have a lot of marketshare, but there's no question they are in a serious downdraft. It would be completely normal for any company in this situation to put itself up for sale. I'm a little surprised Google choose to buy Motorola Mobility rather than RIM, given that RIM has a lower market value and has more attractive assets.
Regardless of what it says in the press I imagine finding a potential acquirer of the company will be the first task of the new CEO.
