Most likely will do that. I think I bought my first PS4 a year after the release. But that was because my PS3 had issues. I might wait a few years. By then I should have a good stable of games and not that much free time to devote to a new console right away.
Especially if they come up with an upgraded graphics like 8K or something with a Pro version. Than you pretty much need a newer television to go with that. I just bought my current TV a year ago. So I'm satisfied with it for a few years. I didn't even planned on getting the Pro. I got it as a gift from my girlfriend. I can definitely tell the difference when I move my pro to a different TV.
