We may find that all this discussion is moot anyway if devs start offering up a 1080p60 or 4K30 mode now there will be two consoles to cater for.
I'm hoping this will be the case, I see no reason why they can't offer the choice now.
It would also be nice if they could allow us to adjust post processing effects such as motion blur, chromatic aberration, depth of field, lens flare, film grain etc.
