I'm pretty sure Sony is investing as much in the glasses less tech as any of the other major manufacturers.
But just like with all those major manufacturers, their glasses-less 3D tech is just not "there" yet, so they're pushing the alternative for the 3D enthusiasts who don't want to wait years before they can get the 3D from movie theaters that they became fan of.
This is not unlike any technology advancement out there. Everything gets better and better if you wait a few years.
Nothing wrong with that though. We're all playing on consoles that become obsolete after 5 or so years, for example.
