Q4 2019 is our first viable target for a proper generational leap in console power, but the price of that leap in technology looks daunting. Even in the here and now, the price bubbles in the PC component market are making the high cost of Xbox One X look a lot more attractive. But a relatively large 7nm processor with an Xbox One X-level cooling solution paired with a big upgrade in RAM and some kind of solid-state storage solution? That's a whole new level of expense - and financial viability more than any other factor may well push the arrival of a next-gen PlayStation or Xbox back to 2020.
