Don't listen to those who say it's just a pro, Scorpio is the new generation that's compatible with the old one, MS is going the pc and mobile route, i always make the examples of iphone 6 and 7, different generations but play the same apps, and 2012 pc vs 2017 pc, different generations of hardware but they play the same games, scorpio will be the same with the xb1.
You should be happy for this, finally console manufacturers speculations are going to end, consoles aren't some alien things, they are just closed custom pc, put the same os on them and they will play the same games(well it's not that simple but you get the idea).
