So I got my replacement camera back from GoPro and as far as I can tell the distant focus softness I was experiencing with my last camera (See video here: youtube.com/watch?v=ayYmVeZnknI ) is no longer an issue. To my eyes the cameras appear to have the same level of distant focus. I didn't even test the close focus because A: I'm not interested, and B: It's been raining all week, and as soon as the sun popped out I rushed to get a comparison shot before it went away.
Conclusion: Hero 3+ is at least as sharp as the Hero3 now. I think even a little sharper in some shots! Check the white picket fence at 0:49
