Now that the cat is out of the bag, here is what we know. (Plus, minus or equal signs indicate price shifts or neutrality.)

• Pretty much identical CPU to the PS4pro with its own "evolved optimizations" (=)
• 40CU GPU for scorpio vs 36CU GPU for PS4pro (Scorpio+)
• more advanced cooling solution (Scorpio+)
• 12GB or RAM vs 8GB+1GB of ram for the PS4pro (Scorpio+)
• GDDR5x ram for the scorpio vs GDDR5 ram for the PS4pro (Scorpio+)
• Same HDD size (=)
• UHD bluray vs bluray (scorpio+)

I say $450 since its coming out on q4 2017

Outside the competition...probably.

I'd say $450.

399$

I second this. $400 would likley require a hit on MS's end (might happen, but it's not a strategy they've shown much care for this generation), and $500 would make it a hard sell to anyone not explicitly looking for the best. A $450 Scorpio would be close enough to the Pro that the "most power console" could sway some more casual gamers, which will be a necessity for the Scorpio to be anything but niche.

399

499$ probably.

$450

DF reckon it would come in around $499, but I think MS are going to take a hit on each one sold

499
