Some interesting questions arise:

1) Would Sony have dropped the price of PS3 without the X360 competition?
2) Would cross-play be a thing, considering how much Sony was opposed to the idea?
3) Would Sony have implemented backwards compatibily after the PS3?
4) How much would the PS4 have cost?
4) How much would the PS5 have cost?
5) Would Sony subscription service exist as it is if GP never existed?

And I don't think much would have changed on Nintendo's side.

Honestly no, no, possible, a lot, and a lot. 

Honestly I'm kind of curious if any other company but Microsoft could come in to fill the Xbox role? Because otherwise....well it could get very funky.
