Belle update in the pipeline?

Hmmm – could this be true? Is Nokia working on a new Symbian Belle update that is said to beheaded towards S^3 handsets? Nothing is confirmed yet, so this remains clearly in the rumors category, but there were some screenshots in an apparently leaked “secret” video (which obviously isn’t so secret anymore), that shows off differences compared to the Belle whom we all know and love. The video is available for your viewing pleasure after the jump, but the three differences in writing would be changes made to the Toolbar, the NavBar and a “Phone” app thrown into the mix. Why not check out the video and see whether you can spot those differences?
