yeah I mentionned "other" goodies in the collector edition and I would not mind to buy the gale twice (anyway I need to buy it another time for a friend) as the game was planned for multiplayer you can offer one of your version :p
or another good idea would be to do like Blizzard did : when they released Diablo 3, you could get it for free if you bought 1 year of WoW. For those who wanted the collector edition but who already bought the pack, Blizzard offer them to get the collector edition if they pay the difference between the basic game and the collector edition.
In this way everyone would be happy : a collector edition with new stuff available for everyone and the ones who support the kickstarter campaign keep their "kickstarter bonus" and can also purchase the collector edition, all they have to do is pay the difference between the normal edition and the collector edition (as they already paid for the "normal" edition of the game)
anothe solution would be to propose a collector edition and sell the stuff of the collector edition via the Vault which is almost the same than what I mentionned before
