Research In Motion will unveil two new products at 3pm tomorrow to mark the arrival of its BB10 operating system (30 January).
The manufacturer is tipped to launch a touchscreen device first - rumoured to be called the Z10 - followed by a QWERTY product soon after.
The anticipated move is viewed as a bold step to convince the market that it can handle the touchscreen form factor.
The manufacturer will unveil the first two BlackBerry 10 smartphones during a global webcast at New York, Toronto, London, Paris, Dubai, Johannesburg, Jakarta, and Delhi.
The operating system is viewed as a make or break development for RIM, which has seen its market share crumble due to the rise of Android devices, and the ongoing success of Apple.
RIM is promising a device 'unlike any smartphone on the market today'. CEO Thorsten Heins said: 'In building BlackBerry 10, we set out to create a truly unique mobile computing experience that constantly adapts to your needs. Our team has been working tirelessly to bring our customers innovative features combined with a best in class browser, a rich application ecosystem, and cutting-edge multimedia capabilities.'
