It's never a matter of whether or not console devs can "make" a powerful-er box that can "keep up" with PCs. The PC itself is an open system, a console is closed. The parts are decided in advance so they can start mass producing them. Even if they theoretically came up with a super powerful console, it'd be a failure somehow because we've seen people not buy expensive consoles. You saw what happened with the PS3 last gen and the Xloss 1 this gen right?? People aren't paying more than $400 or so for a console. Also, let's say that they do make a next gen console that can provide 1440P/60fps.... Devs will utilize the console to push for 30fps therefore allowing bigger and more detailed worlds, with more complex AI and mechanics going on to make what they desire. You can make literally every single game on PS4/XB1 at 1080P/60fps but then each game would not be the way they were envisioned. Graphics, scale, complexity etc would take a huge hit. Just look at most 60fps and then compare them to 30fps games... the 60fps are usually much more simplistic. You can't have your FFXV at 1080P/60fps with just slightly lowered graphics. You can't get your Uncharted 4's at 60fps. You won't get your Grand Theft Auto games at 60fps. They can very well do that, just be ready to accept that it'd probably feel like a older game that runs smoother. Nobody wants to be playing PS3 remaster looking games on a PS4.
