You do understand that both of these consoles are insanely close in architecture, right? Differences, sure, but I feel like I need to remind you... again... that even with the architectural divide of the PS360 - we still see games look/play almost exactly the same... with insanely different architecture.
Now we have consoles with rumored architecture so close in design - you pretty much can call it before they leave the gate.
Sure, anything can happen, but the chances are slim to none. I wouldn't keep hoping that something magical can happen - you are setting yourself up for disappointment.
From everything we know - your scenario isn't going to happen and again - people are here discussing what we know and not chasing some magical, beyond hypothetical unicorn which has no evidence to support its existence.
