There are some packaging photos of the inserts over at spawn of series one now. Not sure about these now, I'll have to see them when they arrive. I'm still inclined to the THOH set and it appears to be coming out in the early fall, a suitable release time.
It's interesting to see how much series one of the figures changed from this:
SIMPSONS SERIES I:
Dr. Hibbert, Mr. Burns & Comic Book Guy
Homer & Marge
Bart, Lisa & Maggie
Flanders & Squeaky-voiced Teen
Snake & Otto
Disco Stu & Krusty
Homer and Bart Why you little...
Homer and Bart Simple Simpson
Krusty and Bart Kamp Krusty
Marge and Homer In the belly of the boss
Itchy and Scratchy Spay Anything
I think that first set was supposed to be THOH themed too.
Still haven't seen the couch gag on sale, so haven't bought it yet. I don't expect the figures to reach clearance, so I'll have to decide in fairly short order considering how few figures stores are bringing in of the Hanna Barbera stuff (and rightly so, they're not moving well even if they are cool).
