Sony already has a userbase around 2X that of XB1. Microsoft really felt like the fact the PS4 was more powerful at launch was the main reason it has crushed them now for 3 years. This tells me they really think it as simple if they become more power they win. Console gamers are not like PC gamers where they feel they need have the best of the best all the time. Some are, but they also tend to own multiple consoles anyways.
Sony is releasing the Pro because in 2013 the tech was not ready to make 4K gaming affordable, we are now getting there. The Pro is simply a stop gap to allow people who wish to play in 4K a way to and allow them to wait longer before PS5.
Microsoft might be getting into a dangerous cycle for them. If they start annualizing hardware updates they lose their differentiation from PCs. Most of their games are already on PC, so people will start asking themselves why they have an Xbox if whatever they buy this year is obsolete next year. Of course if they start treating them like cellphones this could work, you pay 30 bucks a month for your network access and it includes the hardware which you can upgrade every 2 years, or you can get on the 45 bucks a month plan and upgrade annually.

add me, the more the merrier.
