There have been tons of leaks about this issue, but I wanted to see it for myself. I can't wait to get the box set and paint it all up.
A few things I've noticed so far:
-The free mini is not push fit. Glue is needed (and from what I can see in the issue the AoS box set guys are the same)
-40mm base on the sprue, so these guys are practically Terminator size.
-Really nice detail on the model, as reported elsewhere.
-No pictures of Square bases in with the epic scenes (all round). There is one picture that shows a square base along side a round one, but that's just to say that you can keep using those.
-Lots of great pics. The online leaks don't do the issue justice... worth picking up if you like pretty pictures.
Update: I've seen some pictures showing the mini's beside space marines and can confirm that this guy is terminator size.
