I'm pretty sure the final version of Ghost Recon will support some form of 3D; I'm not surprised to see it greyed out in the demo as I'm sure the developers are still optimizing the code.
All the Sony TVs that I've seen had absolutely horrible ghosting; even their 2012 models on display at Best Buy are, to my eyes at least, visibly inferior to comparably sized active shutter displays from Samsung and Panasonic.
Very few games have popout; Uncharted had a bit of it with laserscopes from enemy rifles in a couple of its levels; Resistance 3 had a bit of popout when enemies used certain weapons against you; Killzone 3 also have a few areas where things in the environment seemed to pop out (although the resolution was really bad in that one). Avatar was an earlier side by side 3D game that had some popouts, mostly in the way of foliage in the foreground and such.
If you have an Xbox 360 and want to see a really good example of popoout in a videogame try downloading the indie game 3D Infinity from the Xbox Live Marketplace. You can try the first level for free or buy the game outright for $5. It's a relatively simple first person on-rails shooting game where you pilot a ship thru various levels. It uses side-by-side 3D but the sense of depth is outstanding and there is a constant barrage of stuff that seems to break the plane of the screen.
Beyond that most games I've tried do tend to focus on depth which is fine by me as well as it does help to pull me further into the game.
