One thing that is in one of the slides using Machine Learning for resolution scaling. (DLSS kind of technology).
i'm not enough of a tech guy to understand much other than:
xbox one 4.8B $
xbox one x 6.6B $+
xbox series x 15.4B $++
with the SSD, case, cooling, ect all being more expensive than xbox one x too i can't see this launching below the $500 the xbox one x launched at. ...and at $500 they are probably taking a sizable loss.
Case/cooling isn't a major driver of costs.
APU, SSD are the major drivers of cost.
PS5's Bom is supposed to be $450.
XSX is supposed to be in the range of $460-$520.
Basically: $500 with a bit of a loss seems like the most likely outcome.
$400 is possible, with a larger loss. Consoles used to take much larger losses, but they haven't this past gen. PS3 had a loss of like $300. X360 had a similarly large loss actually.
If they were as confident about their margins as they were the PS4 gen, $500 seems like a certainty. If they are as confident as the PS3 gen, $400 seems more likely.
