The BlackBerry Onyx has been spotted with a trackpad. Although the Tour 9630 does not have a trackpad, the BlackBerry Gemini 8520 does. This could mean that RIM is thinking of making all devices post 9630 come with a trackpad.
Is this the death of the trackball? I hope so. BlackBerry users have had to replace a ton of trackballs because they get dust/sand in them or they just simply wear out. This new strategy could mean longer lasting devices.
