The Scorpio will likely be the most powerful upcoming released console, but in the end by how much?
Sony makes great hardware and I wouldn't be surprised if the Neo performance is comparable. Even if it is weaker, brand supporters and the game library will still have an advantage in many peoples eyes.
I have an Xbox One and even though the PS4 is more powerful I have loved my Xbox One and the games library.
I am currently leaning towards picking up a Scorpio but if the performance is marginal, it might not make such a huge difference in buyer opinions regardless.
