Research In Motion said Thursday that new phones deemed critical to the company's future will be delayed until late 2012.

Earlier Thursday, RIM said BlackBerry sales will fall sharply in the holiday quarter, providing further evidence that it is struggling to compete.

RIM co-CEO Mike Lazaridis announced during the company's quarterly investors call on Thursday that BB 10 will not be launched until later in 2012 now. That delay can be attributed primarily to the adoption of a dual-core chipset design equipped for LTE.

Previously during the call, co-CEO Jim Balsillie admitted that sales in the United States have been disappointing when compared to RIM's shipments worldwide.

RIM;s PlayBook tablet computer also hasn't been selling well, forcing the company to sell them at a deep discount.
