Battle of Geonosis from Episode II will include 7 figuresThis would be my ideal list:
New:-SA Mace Windu
-SA Jango Fett with swappable jetpacks and removable helmets or switchable balljoint heads
-an arena Jedi that hasn't been done before (
Roth-Del Masona,
Sar Labooda,
Joclad Danva,
Sarrissa Jeng, etc.)
Repacks:-SA Clone Trooper (2003 Clone Wars) -- absolutely a DUH! choice
-Clone Pilot (Saga 2002 or new)
-Coleman Trebor (Saga 2002) or Pablo-Jill (post-OTC 2004)
-Destroyer Droid (some version lacking the arm cannons)
Realistically there will have to be some core characters, such as a Yoda (Saga 2002 most likely). We will surely see one of the Saga Obi-Wans. An SA Padme would be neat, but frankly not in my top 7.
Poggle the Lesser (Saga Geonosis War Room, 2003) is a very close runner-up, but he could also resurface in a Mustafar War Room set.
I'd also like a rerelease of the Saga Wat Tambor, this time with a more accurate paint deco.
How about even a Republic Commando--hey, according to EU they were active offscreen

.
Assuming there are
Deluxe/Ultra and vehicles in this wave:
-repacked Clonetrooper and speeder bike (02 Saga or 03 Clone Wars)
-repacked Spider droid (Saga or Clone Wars)
-repacked Saga Flying Geonosian with Sonic Blaster and Attack Pod
-repacked Geonosian Starfighter (03 Clone Wars)
-repacked Hailfire droid (03 Clone Wars)
-or even the Holy Grail itself:
AT-TE
