Since there had been early references to Boba Fett's costume being old Shocktrooper armor (presumably the forerunner of Stormtroopers) I was expecting to see an army of clones in Fett-style suits someday. I thought IG-88 was a leftover of some droid army as well. And don't forget all that old speculation that "Obi Wan" was really a clone designation.
