http://blog.appfigures.com/something-is-wrong-with-itunes-connect-today/ Yesterday was launch day for me, and this afternoon I noticed my first day sales numbers had been revised down by half on iTunes connect. Apparently the new numbers are the correct ones. Early April fools I guess.
My sales figures yesterday were quadruple what I expect on a good day. I'd better go back and check. EDIT: Just checked. Sales figures quartered from what was showing yesterday. Still a good day (relatively speaking).
