The monitor I purchased from Newegg last week was a Feb. 2013 A00, so I would probably avoid Newegg for awhile if you want the newer revision. One thing to note is that when I called Dell for an exchange of my monitor, they initially were hesitant to give me a new instead of refurbished panel because they wanted to tell me that the warranty of my monitor started in February when the panel was manufactured even though I bought it last week. I believe that I was able to convince them to send me a new monitor, but it was not automatic. The warranty apparently starts from the date the panel is manufactured or the date the reseller purchases it, not from the date that you buy it. If this is the case, it is one more reason to avoid older stock if possible. I believe the warranty starts from the date that you purchase it only if purchased directly from Dell. Seems very unfair to me.
