I'm diggin on these PCC's.
Think about this for a moment... Each 'Commander' has the capability of becoming the torso of a gestalt, that can use any combination of limb drones. Your custom gestalt can now use any of the weapon and armor minicons to make your gestalt even more unique.
How many waves will be out by the holidays? Let's say the series launches in july with a new wave every month after that. that's six waves. If every other wave has a new autobot and decepticon gestalt, that will be 6 sets of 4 drone limbs, 12 arms and 12 legs, as well as 6 torsos. Lets say each wave also consists of 4 duo's. Over 6 waves that will be an additional 24 torso's and 24 'multitools'.
What do we have so far... 30 torsos, 12 arms, 12 legs, and 24 multitools. It is Hasbro, so we have to assume that 2/3's of these will be repaints. So our adjusted 'unique' numbers are 10 torsos, 4 arms, 4 legs, and 8 multitools.
Those look low to me, but we'll continue.
Pick a Torso, 2 Arms, 2 Legs, 1 Armor and 2 Weapons [duel wielding rules] 10 x 4 x 3 x 4 x 3 x 8 x 7 x 6 = 483,840.
The numbers don't lie. Your gestalt, using 100% unique molds, armed and armored, has nearly a 1 in half a million chance of being replicated by another... and that's before the repaints which will put the 'unique to you alone' numbers in the multiple millions.
Using these numbers and wave assortments, come the holidays, it is possible for the majority of the dedicated fandom to have a gestalt entirely unique to each individual.
That is the definition of Win... at least in my book.
