“Is 10 going to be the solution to retain that marketplace? We'll have to wait and see,” Gillis said. “It's great they set a date, but the challenges are still formidable. It's not an issue of initial demand. It's an issue of sustained demand.”
Gillis noted that RIM's launch of a tablet initially went OK but then demand fell sharply. RIM's tablet, the Playbook, uses software on which the BlackBerry 10 will be based.
RIM said last month the new BlackBerrys are being tested by 50 wireless carriers around the world.
Thorsten Heins, who took over as CEO in January after the company lost tens of billions in market value, had vowed to do everything he could to release BlackBerry 10 this year but said in June that the timetable wasn't realistic. Heins says he can turn things around with BlackBerry 10.
The new BlackBerrys will be released after the holiday shopping season and well after Apple's launch of the iPhone 5, expected to be Apple's biggest product introduction yet.
