I do remember SSS, but recently I had spot-checked a couple of newish Sony models, and the indications were that the IS is lens-based. Are you saying that there are some recent Sony ILC's with SSS? That'd be sweet!Use a fast enough lens and you won't need IBIS.
As for Pentax being the only mfr with an APS-C camera that stabilizes for all lenses. You are forgetting about the company that came out with IBIS before Pentax. That company is Sony. The A100 beat out the K100d by a few months. It worked with all lenses. Sony IBIS still does. Back in 2006 Sony SteadyShot was considered better than Pentax SR by many people. Comparing their 2013 versions, many people are still of the same opinion.
