UPDATE 1-RIM shares rally as optimism around new devices grows | ReutersNational Bank Financial analyst Kris Thompson boosted his price target on shares of the embattled BlackBerry maker to $15 from $12. Thompson argues there is more money to be made in the stock, ahead of the early 2013 launch of RIM's make-or-break new line of devices powered by its BlackBerry 10 operating system.

"The new management team is executing by maintaining the BlackBerry subscriber base, managing costs and cash, and seemingly readying a February 2013 BB10 global platform launch," said Thompson in a note to clients.

Thompson said he now expects RIM to ship about 35.5 million devices in fiscal 2014, up from an earlier estimate of 31.6 million.
"The shipments boost reflects about one more month of BB10 product availability plus a little extra for the positive sentiment building in the industry from our discussions," he said.
Wooooahhhh ! :D
