No blur will ever matter. Whatever you're focusing on should not be blurred, so if something in the distance is blurred it doesn't matter.
Actually if something in the distance is blurred and you happen to be focusing on it, then it will totally ruin the graphics. So any blur, anywhere, is a stupid idea and should not happen. Your eyes will provide all the blur necessary.
The only reason you'd need blur is to make screenshots look sporty so idiots say 'Wow look at that blur, I'm preordering this game with the fancy blur effect that I'll never actually see when I'm playing it, and if I do see it, it will completely ruin my experience'.
Honestly, gamers are such suckers. Let's see if they improve the gameplay at all. Removing 90% of the cutscenes would be a good place to start, because 90% of the cutscenes are too long and are extremely poor-quality cinema.
