Let's back up for a bit. Next month, as expected, Playbook 2.0 will be made available and will include important things that were missing from the OS at launch. In April, RIM is expected to honor the first year anniversary of the BlackBerry PlayBook by releasing a 3G+ (HSPA+?) version of the 7 inch tablet. In December, you can expect to see a 10 inch tablet with LTE 4G connectivity.
Sometime between now and the launch of the 10 inch tablet, RIM will rollout a couple of BlackBerry Curve handsets. One would be aimed at the developing countries in the world and have EDGE connectivity. In April, the Mobile Fusion service management tool will be launched. The tool allows IT administrators to remotely control BlackBerry, iOS and Android devices. A PlayBook administrative service is expected during the Summer.
The roadmap is not considered complete and doesn't include any new BlackBerry 7 devices. With BlackBerry World coming in May, hopefully RIM will have some prototypes to display as time is ticking against the Canadian based manufacturer.
