Picked mine up at Best Buy this morning at 9 am. There were about 10 people in line. Walked in, picked it up, paid for it and walked out the door. Very nice retina display, but I haven't come across many new features yet.

UPDATE:

My new iPad 3 has light coming in from around one of the edges as if the inner part of the iPad has separated from the outer frame. Very annoying. I think it's a defect so it's going back to the store. Wish me luck!
