I'm afraid so, although it would be neat to see him stick around a little longer...similar to what they did with Shane.
Abraham might be the one to go, but I'm still leaning toward Glenn. They focused a lot on Maggie's pregnancy, which goes along with the comics. Also, unless it was a purposeful misdirection, Maggie is the one who says, "It's gonna cost us something," when they were discussing a deal with Hilltop. I think that was some MAJOR foreshadowing there.
Oh noes, not Glenn! That dude helps tie the group/show together for me. I can live without Maggie but Glenn is another story. Oh well, no one is safe right?
I'm thinking Morgan, Abraham,....and Glenn.
