8bit, that would be cool. lol
Nya, that's a very, very terrible ending. Terrible in a good way. lol, and seeing how the anime doesn't pull its punches.. its a likelihood. As much as it kills me to say this, I hope that actually happens. It would be cool to have a series end that way. A bit brutal, but cool. Puella Magi is a seinen anime, so its very possible. My only gripe is that its almost over, and Madoka hasn't become a Puella Magi still. And I've been fiending for it since I first saw the opening.
Maybe everyone is brutally killed, and Madoka uses her wish for something and then takes the burden of fighting all alone. Hence, how in the opening she's in tears, alone. That symbology has to be for something. The whole opening gives you that feel of her being alone. Even with the scenes with Mami and Sayaka.
