I dont understand why the developers or the publisher haven't spoken about the Deluxe or the Imperium Editions. Are these editions only for Europe or no? I live in the U.S. and I would like to get the Imperium Edition. I do understand that these editions were up for pre order at one point but now I cant find them in any of the major game retailers here in the U.S., only the standard edition I can find! 

I can't speak for Playstation, but I did speak with Microsoft about my pre-order because the game also disappeared from the XBL store. They said that my pre-order was still good so what I'm thinking is they shut off any new digital pre-orders for the game, but will be honoring past pre-orders. Of course, I've also seen some people say they got an email saying their digital pre-order was canceled, so who knows?

Your not alone.... am wondering the same thing, I really want to preorder this game. Add me to PSN: Arbormancer
