What will be the limit?

Perhaps a true 3D game. Maybe a game , and yet to be invented hardware, with an interactive holographic image. One could manipulate the holograms by a virtual touch and handle virtual objects.

This is close,

Ray tracing (graphics) - Wikipedia, the free encyclopedia

but not possible on today's hardware, at least at anything that would resemble playable frame rates yet.

This is the first thing I thought as well.

That and improvements to tessellation for textures. I could see a mix of raytrace and tessellation being implemented together Either depending on the object or environment being displayed or a setup where an image is being created realtime as a raytrace and then updating the tesselation textures overlaying objects to match the image that would be displayed.

Full ray tracing would be far off. It would look sweet though

There were some mentions in the article that were promising though: http://en.wikipedia.org/wiki/Quake_Wars:_Ray_Traced

Also this looks pretty sweet...
