If this happened it would be nice if I could just take the hard drive out of my PS4 and place it inside the PS4.5 without losing anything. I would be hesitant to part with PT due to a need to reformat or something of that sort.

I was in a relationship that was non-monogamous for about 4 years. I'll confirm it's exhausting, but this is mainly why: because it takes up all your time.
