I'm not going to get in until the 16th, and I completely understand why. Hell, I don't even really mind it, 4 extra days is pretty awesome.
That being said, the the lack of communication from BioWare added unnecessary aggravation to the process; I wasn't expecting to get in early and I even found myself getting angry over the early access process. Now that we're getting consistent, informative communication from the devs I notice a remarkably huge change in my attitude. Seriously, I went from seriously annoyed to happy and content as can be in an instant. The simple act of giving us ball-park estimates of what pre-order dates will get in when cannot be underestimated, and frankly I'm surprised they didn't just start like that from the get-go.
