Microsoft and Samsung are the two most likely candidates to take over the Canadian company, Misek said. If BlackBerry's launch is successful, a takeover price would be around $20 to $30 for RIM, he added. If not, his forecast dropped to the $5 to $10 range.
Misek think Samsung may want to buy RIM because they are "trapped in the Google ecosystem" and at some point "fear that Google will compete directly with them."
RIM has struggled in recent years to compete with phones using Google's Android system and Apple's iPhone, but Misek sees hopes for BlackBerry 10.
"We actually think that BB 10 is a solid operating system," he said. "What's neat about it is it actually can actually emulate Android apps," he said.
At the launch, the BlackBerry platform will have about 100,000 apps with an additional 200,000 to 300,000 Android apps that will be available on the Android player, he added.
"It actually does provide some advantages that current Android OSs do not," he said.
