It wouldn't have changed much. The consoles were planned long enough before the pandemic and the shortage that designs were pretty final. They would have launched with more stock in the beginning, but the units shipped till now would be the same. There still would be a shortage.
Also, I think the launch situation for both consoles is pretty good considering the launch of their predecessors. The lack of stock is the biggest problem and in a year or two multigeneration games will slowly fizzle out as they have during the previous generation switch.
