No such update is planned for the NR636. What this means is, the TX-NR636 will give you full Dolby Atmos multidimensional sound from Atmos-enabled discs (as well as True HD / lossy Dolby tracks) , but will produce only DTS-HDMA 7.1 tracks (and its DTS lossy variants) from DTS:X discs. My advise: if you care for multidimensional sound, get the TX-NR 646 to future-proof yourself. Movies won't ALWAYS use Atmos, they may use DTS:X, too. And X may even become the dominant multidimensional audio format for the next few years (just as DTS-HDMA became the dominant lossless audio format last few years). BUT if you don't care at all for multidimensional audio / ceiling & reflective speakers and stuff, there are some other great amps on this same price range that don't feature Atmos / X but compensate on power / other features to give you a better bang for your buck. **Q: On another site a customer said that the zone 2 speakers could be used to make this a 9.2 system. Wrong info?** A: No. Never possible because it only has 7 amplifiers, meaning it can only power 7 speakers at one time.Why bother with Zone 2 outlets at all? I don't always need all 7 channels for watching TV, but I still want to listen to music in the kitchen (while preparing snacks for TV!). I can pre-wire the sound for the kitchen and drop the TV down to 5.1 while rockin' in the kitchen, then lose myself in Atmos or DTS:X sound. While the kitchen solution does not lend itself to a separate amp, Zone 2 can be configured with a "line out" to a vintage receiver (or cheap amp) without sacrificing any speakers in the main zone.The system is simply not designed to support 9 channels. You'll have to shell out a LOT more money for that capability. **Q: Will the Onkyo warranty be covered if fullfilled by Amazon but bought from different seller?** A: As long as the seller is an authorized dealer(we most certainly are) you are covered by the Onkyo manufacturer's warranty. If you have a warranty claim you use the seller's name as who you bought the product from, not Amazon. **Q: Will Chromecast work on this?** A: Our Chromecast never works with our TX-NR646. So frustrating!!! Has completely ruined our theater experience.
