Is glenn really dead :'(?

Or did he do some badass zombie evasive parkour while they ate the other guy? That was too much of a quick death for a guy who's been there since the beginning of the show.

I want him to be dead, because getting out of that is ridiculous.

But he wasn't given an obituary on Talking Dead and he was photographed on set with a character that hasn't been introduced yet. He's alive...
