Lots of great suggestions guys. Thanks for all the input.
I've already prewired it for a 7.2 set up. I am not jumping on the Atmos wagon most likely ever. Bought a Denon AVR4820 CI to run it all. My HT speakers are all Klipsch, so they are not a huge load on the amp section. Am probably going to purchase a Sony VPLHW40ES projector. Don't think it does 4K, but once again I got over being on the bleeding edge of HT technology a long time ago (and the premium price to be paid for the equipment). However, will consider a 4K projector if anyone knows of a great one in the $2000-2500 range. Since am already paying to build a new house, the money supply is limited.
Pepe, am planning to buy a Carada Criterion fixed screen. That is what I had in Pgh and was very happy with it. A 134" runs just a hair less than $1000.
