I feel like your proveing his points.
MS xbox series X, is a BIG thick boy, and is obviously designed such for cooling purposes (itll draw in air from below/sides/back and push it out the top of the case), and wastes very little (if anything) in terms of space by its design. Microsoft are obviously going for "we just need a huge fan, 120mm+" and that ll be it (we can save abit on metal of the cooler designs, by useing a bigger fan instead).

While the OP picture, looks like some bad PS4 slim design that just looks wrong.

Playstation 5 will also be "big" imo..... if MS has to build it that way to keep it cool, the PS5 will also be big or designed around cooling.
(even if its rumored to be abit weaker, the differnces wont allow for one to make a slim design, and others have to make a gigantic one)

Its a ugly design that doesnt make sense. Its no ones thing, everyone here seems to hate it too.
So theres like a 99% chance its fake :) no worries.

I doubt Sony would choose a desing that doesnt make sense, and that everyone seemingly hates.
Their smarter than that.
