I read it was touted for September release, got to be shown at E3. I'm happy to see the scorpio from MS before i make a decision, which ever is more powerful will have my attention.
You'll be waiting a year or more for Scorpio.... by then so many people will have bought Neo that it will be lead platform for developers.
Sony will probably launch another upgrade for late 2018 or early 2019 if needed.
Plus Xbox no longer has any exclusives...all hit PC too. No Japanese games either...
