Yeah, I think I will. Not straight away, though.
It's pretty plain that the extra 1080p-version improvements are going to be standard going forward, with the leaked documents stating that every PS4 game released after October will have to have extra Pro functionality. I don't intend to get a 4K/HDR TV set since I only got my current one a year ago, but even looking at those Rise of the Tomb Raider options illustrates that there's to be a lot of scope for technical improvements even at 1080p. I've a lot of PS4 exclusives to look at starting next month, so I'm certain I'd get the benefit of the new console.
