Man £649 just seems crazy in this economy. Especially with it looking like the new One X RRP will be £259 with a drive.
I hope I'm wrong, but Sony hasn't really been known to lowball hardware prices.
But to be fair no compact cooling design would work for these power levels, so they have had to make it large. The Series X is just literally a big square box with a huge fan and cooler at the top, not exactly hard to design that cooling was it?
It's a clever design to keep it compact, it's smaller than the Original Xbox One.
