Maybe it's something I've missed here, but why do we care if we have game over screens or not?
It feels like someone just needs a reason to further hate on the modern games, so now their bashing their lack of game over screens.
I never cared for those screens, so whether their there or not, I don't give a damn.
Edit: Also, when I first thought of game overs screens when I read your title, the first thing I thought of was the "Epic Fail" thing that pops up in Bad Company 2 nultiplayer when you die of suicide, accidental or not, and I remember now how much I hated it.
