Do you know about how many of each are dropping for the 3663 and 3665? Also, have any idea on when the 3667 will drop next? Unfortunately, I didn't know about the 3665 so I am way down the list on that one (past 150 according to the community sourced list). I am so close on the 3667 list so I should get my notification when the next batch drops, but the waiting is killing me.
