From the Capcom-unity blog:
As you may well have heard by now, the title of Revelations is indeed misspelled on the spine of the game box (as "Revelaitons"). Unfortunately, the initial North American shipment of the game will reflect this error, but we just got confirmation that subsequent shipments of the title are being repackaged to have the correct spelling. Meanwhile, customers who have received the misspelled version can contact our Customer Service line at 650-350-6700 or by email at firstname.lastname@example.org and we'll send you a new insert for your case. So yay!
