From some of the files in the camera, there’s a string saying what the camera driver was built for containing "8250" which I assume is the processor (MSM8250 is the Snapdragon SOC used) and "Star" and "ThunderStone". (This is from camera.exe from the latest Leo ROM)
\Perforce_AutoBuild\WindowsMobile\Camera\CameraProjects\HW\QCT\8250\Star_PPC\Windows Mobile 5.0 Pocket PC SDK (ARMV4I)\Release\ThunderStone_PPC_VO.pdb
I was also speaking to someone a long time ago, and they said the Star was being worked on very closely with MS to cover up all the settings, and a few other "surprises" as he put it. That ties in with the Leos Settings Enhancement, and with the capacitive screen.
This all leads us to an interesting conclusion, that the SuperStar (possibly Tegra based) may still be in the worksâ€¦.
