I'd say either finish the ethernet wiring and stream it. In fairness I don't think the PS4 version will be drastically different from PC as much as the difference between Fallout 3 or Skyrim between 360/PS3 and PC, but if you care about mods then they'll obviously hit PC first.
This is definitely a couch and controller game though, I can't handle 200+ hours of Wasteland exploration in an office chair at a desk.
This is the prime reason I'm exiting PC gaming. After spending 8-9 hours a day in an office chair at work, the last thing I want to do is spend even more time sitting in one when I get home.
