We don't even know what the Scorpio is going to be... MS just said it'll be 4K gaming ready and top of the line and capable of 6 tflops. But given what kind of PC set ups are needed for 4K gaming, I can't imagine it'll be cheap, even with promising (and cheap) new tech from AMD.
I'd wager Sony is holding back the Neo because it seems kinda ill-conceived... just trying to push 4K steaming (and no UHDBD support).
EDIT* Actually, some of the quotes from MS are just

ing hilarious. This sounds like market-speak to me.
- "These are the highest-quality pixels anybody has seen."
- "This is the console developers asked us to build; they wanted a console with no boundaries, had no limitations."
- "This console is a hundred per cent for you guys. We read the articles, we read the reviews. It's the 'we heard you' console."
Granted, you can't just scale/multiply these things, but just for comparisons sake: the Xbox 1 is capable of ~1.2 tflops... so, the Scorpio is going to be approximately 5x more powerful.
I was wondering if Kojima showed anything... guess I got my answer.
