To be honest Europe has several different currencies unless you are refering to only the European Union where the Euro is used. This means that Nintendo needs to price it differently depending on which country you are in. Chances are Nintendo did reveal a suggested retail price for each region but didn't want to go out and list all the different prices and regions seperatly. Chances are retailers won't gouge either because they know how much it costs them to buy them from Nintendo and they know their competitors will try to offer a low price to sell units.
Keep in mind a suggested retail price does not prevent price guaging. If a retailer wants to they could sell the unit above that set price or below as they so choose.
I think Europe will probubly get similiar pricing to NA or Japan maybe between. Either way it won't be to drastic of a difference I'm sure. Also don't complain to much you guys get the 3DS before us North Americans. You finally get something great before we do, be excited yay for you!
