Maggie and Glenn are both part of the same wave - Series 5.
ToyWiz also has a new pre-listing up for Series 6, check this out:
Bungie Guts Zombie
Somewhat surpised to see Abraham on the list since he hasn't even been introduced on the show yet. Great to see Carol and Hershel on there though, was worried we might never see them.
They also mentioned a 10" Rick figure for October I believe.
That list for Series 6 sounds almost too good to be true. I wouldn't complain if it ends up being real though. Hershel and Abraham in the same wave would be killer.
As for 10" Rick... I might have to pass on that. I just opened the Daryl figure this evening, and I must say I am extremely disappointed. It was extremely difficult to get the crossbow and poncho into place on the figure, and I have trouble keeping it balanced (possibly due to the poncho). I expected easier display from an unarticulated figure.
