I would put money (my usual shiny nickel) on these being more repaints of the Deluxe 3-pack Clones. Why?
1. Hasbro always takes the easiest and cheapest road when it comes to exclusives. 90% of the exclusives these last few years have been repaints or slight retoolings of previously released items (at least in the 4" line) and I don't think this will be any different. It's easier and cheaper for them to simply repaint the three pack Clones than it is to come up with all new packaging for a three pack of SA Clones with new paint schemes.
2. If the idea of a SA Clone body being used for a special three pack was actually floated by Hasbro, TRU probably balked at it, since they couldn't understand how three of the same exact figure in a box would sell that well. Then Hasbro told them they could have the cheaper three pack, but it would have three different poses. TRU probably jumped at this idea, not realizing that while it offered more "variety" to the uninformed consumer, it probably cut their sales (and repeat sales of the same item) in half, if not more.
3. (Conspiracy theory): Hasbro is putting these out there so they don't have to do them again in the future. This way, they can say, "We already did those and they didn't sell to well, buy the 400th Luke/Han/Vader instead" when someone asks them to do regular carded versions of the three different paint schemes.
Everybody tells me I'm a pessimist and a cynic, and I admit this is true, but it's hard to be truly disappointed when you always expect the worst.
When it comes to Hasbro, that is what I have come to always expect.
