I found James Loudspeakers is doing a DTS:X demo (and an Auro one, but I've never been impressed with Auro).
There are several major players with laser projection this year. Shouldn't be hard to see a few.
I am going to check out Vizio's booth as they are going to have a 120" TV with High Dynamic Range and Dolby Vision. You should buy one, they are only $120,000 USD.
Now to find a "quantum dot" demo.
UPDATE: Vizio is going to have a 65" version of the 120" mentioned above that has quantum dot technology.
