I guess the only question is will any of the other UK models (discussed by techradar.com) make it to the USA. Techradar speculates maybe except the XG70 - UK only.
So UK models:
XG83 - 43, 49 Basic X1 processor
XG81 - 43, 49, 55 65 X-reality proceesor
XG80 - 43, 49, 55, 65, 75 X-reality processor - Announced for USA - X800G
XG70 - 43, 49, 55, 65 Basic model UK exclusive
So will Sony later announce an X830G or X810G for USA.
I say not, but Techradar thinks maybe.
For non-4K Sony has the WG6/W66G - likely would be a W600G /W660G.
