I don't know about that... there's chatter that Sony was concerned about the response to Backwards Compatability after the reveal event and they're now scrambling to do something to save face and compete with what MS has been building for a generation.
Add in other aspects like XSX being the more powerful console, multiplayer going free while Sony will still require PS+ at this point, and Gamepass and I'm finding it hard to see why anyone would rush out to buy a PS5 at launch, especially since nothing they have announced that's first-party/exclusive (at least on console) is going to be available at launch. Buggsnaxx? Shut up and take my money!
