U2413 ordered this week, received rev A00 (current rev is at least A02)

I ordered a U2413 monitor earlier this week and was surprised to receive today a rev A00 unit with a manufacture date of April 2013.  Since this monitor is currently on at least rev A02, I figured if I ordered it directly from Dell it would be the latest rev.  Needless to say, I very surprised that wasn't the case.  I'm returning this unit next week.  I'm still interested in buying an U2413, but only if I can get the latest rev -- how can I be sure to receive rev A02 or later?  (Btw, I sent my current order number and serial number to Chris M. via PM.)
