Homatics Box R 4K Plus or wait for S905X5M

Hi all, I'm trying to get a new Android TV Box and have a few criteria:
AV1, Dolby Vision, Dolby Atmos, DTS:X passthrough and AI upscaling(nice-to-have).

I know the current generation Homatics Box R 4K Plus (and its clones) support all this, bar the upscaling.

Would I be better off waiting till the new gen S905X5M boxes release to get all of this (will they even support DTS passthrough?), or just forget about the upscaling and get the current gen now? I'm in the UK if that makes any difference.

Thanks

P.S. (Nvidia, plz release a new Shield and rid me of these problems)
