This idea that developers will skip the Xbox consoles because of requirement to release on the Series S is ridiculous. Developers are businesses. They will do whatever the numbers tell them to do. If there are a large number of Xbox consoles in existence, and it appears that there will be, they will do whatever they have to do to get the games to run on those consoles.
Maybe this will impact the math for devs/pubs enough to make it a teeny tiny bit cheaper for Sony to pay for exclusivity for games. But, that's going to be a very marginal issue.
The argument that Series S will hold back the entire generation is more reasonable. Developers will know that they must make their game run on Series S. So, they might not do things that they otherwise would if they only had to worry about PS5 and Series X.
