I don't get your angle of not wanting to counter my point. An easy rebuttal would have been that "the market decides!", and in NA - as it stands - they've decided it is exactly as Xbox have stated, that it is a next-gen system.
My rebuttal would then possibly be that the market is still to decide, and we'll see when the number of households in NA (and further afield) where a PS5 is bought after a XsS, and then we see the relative market share by digital/physical software sales, and subs.
I don't dispute it is released as a next-gen system, but for my miniscule contribution to the market deciding, I disagree personally, but am happy for everyone else to agree with Xbox, if that's what they've done.
