IMHO object-based audio rendering will take off. The studios like it and unlike 3D it doesn't require extras on behalf of the audience to enjoy a considerably enhanced experience.

I think getting on board with Atmos is a bit of a gamble before DTS shows its hand. I plan to add height channels but I want to ensure that their positioning etc is compatible with future formats. I also have no plans to ditch my Meridian system and will 'integrate' a 5.1.4 system with my 861. I'm going wait about 6 month before assessing the options. I won't be missing much as current Atmos releases are truely woeful.

Edit: Jaco - good choice on the 7702, it looks an excellent processor
