Sony released the PS4 Pro on Nov 10th 2016 and the teardown video of that looks to be posted on youtube on the 11th. So if history is anything to go by....
You probably should re- think about making conclusions based on information missing, just because you have your wishes. This is Sony's playbook not yours, they will release info, either dumps or staggered according to the strategy they think is the best one. The rest of us, can just armchair and tear them apart with a 2020 hindsight.
Sony has said they want to transition people from PS4 to PS5 faster than any previous generations transition. That does not chime with a limiting stock play. Especially if XSS/XSX is available in abundance, they will most likely loose even more money that way.
