We just reported about leaked slides for the upcoming touchscreen BlackBerry Thunder. The BoyGeniusReport has even more leaked information from RIM that details the BlackBerry product positioning and upcoming future BlackBerry phones. Looks like RIM needs some urgent consulting from Apple on how to keep their people from leaking stuff.
The density of the leaked BlackBerry material should be even a very revealing read for Apple and other RIM competitors.
There is just everything in there from market segmentation to competitive positioning.

The document is a bit confusing if you do not know to match the internal names to the marketing names of the BlackBerries, even I have my issues keeping up with those code names.
Especially as RIM uses different codenames for the same phone just for different carriers. The new BlackBerry phones that come this fall and in 2009 mentioned are the Javelin, Niagara, Thunder and Meteor.
