I've only read that the Qualcomm processor is similar to a Cortex A8. This is my guess: The Pre2 supposedly has a TI OMAP, similar to the N900, and it runs webOS 2.0. The Pre3 will run webOS 2.2. If they're going to make a huge change to the architecture, wouldn't they name it webOS 3 or similar? What I'd really like to see is all the old games get updated to work at 800x480 so a lot of the preenv workarounds could get cleaned out.
