From what I've been told (by a fairly reliable source that works in the film mixing industry is that home DTS:X only has a maximum of 16 objects, which are really more like "channels" that can be assigned a location out of 34 possible supported speaker locations (two of which are LFE channels). Neural X then figures out where to create "in-between" channels to simulate more between or around as best it can (unlike commercial DTS which I believe uses real objects as does Auromax). I'm not certain if that includes the normal 7.1 bed channels or not, but then all the rest of the 34 would have be extracted. That's certainly doable (e.g. I create "top middle" by using Pro Logic processors to extract a "near discrete" center-channel output (it removes the center output from the front/rear as well so that's what I mean by "near discrete" as you typically can't hear the little bit of leak-through). In fact, it works so well I'm not sure more 'objects' would make a noticeable difference in a home environment with a 32-34 channel maximum limit. Two different ways to achieve the same thing, really except that "channels" don't have a max limit on how many individual sounds you can pack into them at one time. Atmos actually has a maximum for the non-bed channels, but I think you can combine sounds to get more.
There's been a lot of claims early on by DTS that made it sound unbelievable that have never surfaced in reality including that horrible 11-channel maximum limit that's been present in the home version until now. But so far only Trinnov has announced support for it and I don't think it's available yet so we don't know for certain what it will do. Most over at AVS seem to think it will just allow Neural X to create all the remaining channels out of 34 maximum (two of which are LFE channels). Atmos, meanwhile can do 32 + LFE maximum speakers, I believe, at home and Trinnov has found a way to expand that (probably using something similar to Neural X) to 64 (same as the commercial version, although Atmos at home has a maximum number of objects as well that are then "co-located" with other nearby objects. I know Atmos has a way to convert the cinema master tracks to a home version that can then be tweaked, saving time. I'm not sure about DTS tools, although I think I read it can make one cinema master that can then be easily converted to Auro and Atmos as well. They all have similar speaker counts at the theater level (using Auromax instead for Auro at least, although it has "true" bed channels at the theater closer to ear level than Dolby, which actually uses "side heights" for "side surround" in cinemas, contradicting the home version quite substantially IMO. I'd think Auromax would be superior at the theater if mixed for it, but I've heard most Auro-3D theater tracks are just "print downs" of Atmos tracks so they sound similar anyway.
