No specs yet, except you don't need extra base station as it will have inside out tracking, but still tethered.
PC specs suggest the resolution won't be great, (4GB ram, 4 cores, DX12 compatible gpu)

It's targeted to be made by 3rd parties, like the Steam box. So specs and price will probably vary.

but that is not wireless...
