I think you will better serve yourself by researching this yourself besides asking here. I say that because, with a little research you should notice little updating going on here so "new hardware" is one thing which doesn't show up much here. Especially since the original authors of RGBDemo have moved to a corporate site and that corporation does not pay them to support the Linux code base.
Research will also give you insight as to who now owns the patents to the PrimeSense designs which RGBDemo was based on and why we are not seeing any new devices on the market.
