*Updates referenced in the OP and posts are based on VG Chartz hardware number charts that are still showing PS5 over tracked. Hopefully in time, the charts will reflect the best possible estimations from the available data.
It has been a while since there has been any updates worth mentioning, but here we go. It took a lot longer than I thought it would for the Switch to pass the PS4 but it finally happened. Originally thought it would occur at the end of January.
The gap between the PS5 and Xbox Series hardware sales is shrinking at a steady rate and may be smaller than what is reflected in the charts. But it does seem inevitable with current supply chains, that the PS5 will be overtaken.
I will try to add some spice to this thread during the times that no position changes are occurring to keep it more active. One way to do this is by adding a poll to the thread, that I will archive in some way after some time has passed and add new polls with the ebb and flow of the North American hardware news.
