agree, luke will be first to go. but i disagree about ig88 warming, i think he'll be one of the hardest to find
i can see him being one of the hardest to find to...im just talking about the stores in my area though. when the vintage first came out...there was half an aisle literally jammed packed with vintage figures. luke was the only one to be sold out...on the first day, then the scout, the other three figures were left on the shelf for a good month or so before it was down to only greedo.
im just basing my guess that Boosk and IG-88 will warm because one of them is an aliean the other a droid and none of them are main characters. then there is the fact that if they are shipped with more in a box then the snowtroop and luke they will be easier to get, and there will be more left on the shelves.
and of course remember im just talking about this based on my area. for sure though after a month that this line is realesed they will all be hard to find.
