If Sony invested in a more powerful console then Microsoft invested in another more powerful console at their turn, if Microsoft is allowing devs to do exclusive games on Scorpio, why would you think Sony wouldn't do the same for Neo?
Because they have different strategies and don't have to follow each other?
Sony was going to supposedly do this regardless of what MS did, they both wanted upgraded units.MS is the one saying that the era of generations is over for them, and Sony is the one saying otherwise.
