Just tried to register for Lotusphere. Early Bird fee is 1.395,00 US Dollar, which equals right now 1.112,27 Euro. Submitting the credit card information links to a new page, where you have to confirm the purchase showing an amount of 1.395 Euro. Not Euro US Dollar like in the picture I took later from the first registration step.
1.395 Euro is about 1.749,60 US Dollar. That is not what I expected to pay.
