Jeff - you mean different from Vader and the 5-pack of cases clamshell or different from previous releases of the SA Clone?
It is a third style clamshell case.
Style 1 - came with the Lava Vader and Target 5-packs
Style 2 - came with the Clone Trooper. It has Vader Emblems on the "Locks".
Style 3 - came with the Clone Trooper. It had Clone Emblems on the "Locks".
Someone reported somewhere around here, but I can't remember who it was.
I can take a better picture when I get home tonight, but for now this image (borrowed from GalacticHunter) should clear up what I mean:
You can see the first case the Clone came in had "firey crosses" on the locks of the case, the same emblems that were on the lock-nubs of the Vader case. The new version of the Clone Trooper case has what looks like a laser bolt of something on the little locking nubs at the top.
