It makes some sense, most people won't be able to afford a 4k TV anytime soon and so won't care if their new console is 4k capable. And then you will have the crowd who just wants a future proof console, or will buy into 4k immediately or relatively soon, and those people will want the 4k version. The 4k version could have beefier hardware for the extreme resolution output, while the PS4 can just have enough to kick 60fps at 1080p. So you get to choose between the $300-400 console, and the "$599" console.
The big question would be how quick game developers themselves would be at releasing 4k resolution games.
