Analysts worldwide were stunned last December when Research In Motion announced that its new line of BlackBerry phones would be delayed until the end of 2012. RIM attributed the delay to the development of a new microprocessor.

But analysts are not buying the company's explanation. They believe that the new phones along with the Blackberry 10 platform could be facing critical performance issues and technical glitches, forcing RIM to delay the release.

The delay comes in the wake of the smartphone market heating up. The new phones are aimed at reversing RIM's rapid loss of market share in North America.
