I've been looking at the animation on the Revetech site...

I see way more contact points + gears + sliding things + torsion loads per piston than a regular con rod set-up, so if in fact there are gains with this design they have to be from the mechanical advantage more than offsetting the increased internal friction. And then there is the expense and longevity of lobes + gearset vs rod and crank throw.
