I tried an Occulus a while ago and found it to be quite unrealistic, digital and "fake." (And I only had it on for about 30 seconds but my eyes felt a bit sore afterwards!)

Once LCD density allows for VR with 4K (or, if needed, 8K) per eye... yeah :) we'll firmly be in the virtual reality revolution.

Obviously we'll also need tracking and rendering that can keep up but display density is one of the trickier problems right now.
