Wow, I guess I'm the only one still buying these around these parts....
Anyway, one of the local WMs had a huge pallet/aisle obstruction in the middle of the floor with the new "Ultimate Battle Packs" on one side (equal numbers of each of the three) and those Galactic Heroes 12 packs on the other side (I didn't bother to count those). 19.76 for each on both sides.
Now, modified after further inspection, is the list of differences between the figures included in the 10-packs and their regular issue 4-pack versions, where applicable:
-Mace Windu is the Order 66-Jedi Masters Mace with the base repainted in orange
-Clone Commander has a new head and is a repaint of the Utapau Clone Trooper (Firing Pose) with an orange base
-The 3 Clone Troopers have new heads and are repaints of the Utapau Clone Troopers (Firing Pose, Running Pose, and Standing at Attention pose) with orange bases
-The Battle Droids (both poses) are repaints of the Utapau Battle Droids in pink with orange bases
-The Super Battle Droid is a repaint of the Utapau SBD in silver with an orange base
-The Destroyer Droids are identical to the Utapau BD Destroyer Droids
-Yoda is a repaint of the Kashhyk and Felucia Heroes Yoda with a brown "flight effect", muddier water, and an overall darker look
-The 3 Elite Clones have slightly different deco on their bodies (nothing really notable) but all three have greener bases than the previous releases
-The Wookiee Warrior with dreadlocks is a slight repaint of the WWwD from the Kashyyyk Wookiee Warriors set; this version has darker fur and no gray highlights
-The Wookiee Warrior with shield and rifle is a repaint of the WWwSaR from the Kashyyyk Wookiee Warriors set; this version has much lighter fur
-The Battle Droids (both poses) are repaints of the Utapau Battle Droids (with the Hasbro "camo" stripes)
-The Super Battle Droid is a slight redeco (a bit more dirty) of the Utapau SBD with a brownish-green base
-The Destroyer Droid is identical to the Utapau BD Destroyer Droid
-Darth Vader is a straight repack of the Vader from the Imperial set
-Luke Skywalker is a straight repack of the Luke from the Wampa Attack set
-3 Imperial Snowtroopers are straight repacks of 3 of the ST from the 4 pack (the only one not included in this set from that one is the single-handed shooter ST)
-1 Imperial Snowtrooper Officer is a straight repack of the ISTO from the E-Web set
-3 Hoth Rebel Soliders are repaints from the HRS 4 packs (the only one not included is the "awkward running pistol guy") with either brown coats or pants
-1 Hoth Rebel Solider is a repaint of the sitting cannon guy from the Deluxe Turret Box set with brown pants
So, all in all, unless you're an army builder with these (guilty as charged), you could probably pass on these and not miss anything big. If you have to get one, though, go with the Geonosis set, as that one has the most "new" content of all the sets, what with four never before released AOTC-era Clones, and a much better decorated version of the SBD.
