They refer to the 'lenses' as something like active liquid crystal display that can be made opaque or see through (or partially see through) depending on a charge applied to them. They're not glasses lenses as such, but screens that can be made transparent (partially or fully).
The other 'HMD patents' from SCEE also mention this kind of stuff, in talking about possibilities for obstacle avoidance or alert (i.e making the environment visible through the HMD by activating the liquid crystal shutter to let light through if something in the environment needs the user's attention). The application there arises precisely because it's talking about an immersive VR HMD (and not a Google Glass style device), and it might be desirable to have some way to bring the environment back into view if there's a hazard in proximity to the player or whatever while playing some immersive VR game.
We'll see, it would be nice to have AR, but if it is included, it won't be like Google Glass I don't think. It'd be a second use alongside VR.
He teased nothing, tbh. My read is that he was just joking with the editor about getting 'famous' by being in widely distributed CES pictures or memes using some new product - but not some specific product of SCE's. SCE never announces anything much at CES.
