It's funny, because, if Mac were going to allow some information to be "accidentally" leaked about this collection, it seems like the eye shadows would have been the last thing they should have chosen. "Look everybody, it's a bunch of shadows you've seen before, all within the last year!"
I think that there has to be more to the collection than what we've seen, personally. It wouldn't make sense to do a tiny little group of recently seen re-promotes. The shadows on their own would be unlikely to recoup the necessary investment in developing the special imprint, store displays, etc. I know that they work on high margins, but that would just be throwing money away. No one likes to do that...
