I'm not sure how useful the image tracking capabilities are. Not just because I see few opportunities to use those features, but also because I'm sceptical it would work well outside lab settings (not just a bottle being slowly moved across a uniform background). Merging the flash/non-flash images does sound very interesting to me however. I hope Qualcomm or MS finally offer a DSP based solution for HDR photography too.
I'd bet that the rumoured Goldfinger will ship with the S805, still, none of this will be visible to the customer if the OS doesn't expose those features through the UI, so it's still... wait and see.
