Well, then sir you have been mislead by HTGeeks.
Hands down, Atmos was quite the buzz at CEDIA. People are STILL talking about it. A number of skeptics in the "industry" left CEDIA really excited about it.
Is it still too early to jump on the hardware? Yes. I am a firm believer is skipping "generation 1" tech for this kind of stuff.
With that said, ATMOS processing will make even your non-ATMOS movies sound better... At least if they have a Dolby HD track. Not sure how DTS HD-MA audio will be handled through ATMOS, or if it will did anything with it at all.
Again, don't take my word for it, check around and this is THE jump in audio technology that people have been waiting for since Dolby Surround. Oh, and I was a skeptic of ATMOS too, especially for the home, but I am a firm believer in it now.
Check out this video, or at least the first half of it, where they talk about the best of CEDIA and spend 30 minutes just talking about ATMOS. Home Theater Geeks CEDIA Round Up
