You don't have to buy anything, if reality isn't your cup of tea so be it. It took a year and a more complicated cooling system and an extra $100 to get a 1.8TF advantage for the One X, the new consoles are likely to already be starting with that cooling system, so what's next? and would 1.8TF matter much as much between PS5 and the new Xbox? nope. A wealthy company can't make technology move faster than it's ready to move, these are consoles not gaming rigs, cooling, cost and power draw are all taken into account. An extra $100 would mean IF it were possible to get something better in that APU it would raise costs in other areas as well, sorry but that's just now how the console business works! Both Sony and MS face limitations regardless of how much money they have.
As far as devs being lazy, if you think all it was going to take was to drop the res then you are crazy, if that's "all it took" they wouldn't have complained. The mid-gen refreshes take more work than MS and Sony act like they do, it's not building an entirely new game but it's not just flipping a switch and calling it a day either.
As far as the cell phone comparison that doesn't really make much sense, cell phone manufacturing is done at a much faster rate, console go into production a couple of months ahead of the release date and they never have enough, you rarely see cell phones being unavailable after launch, at least not for long and they go into production much closer to the release date.
