They are supposed to come out 20 mins ago, but people have reported gettin em an hour after midnight too.
Did it manually, works the same, actually a little faster since its a 11mb file you are downloading at 1.5mbps compared to your typical cable speed :-) there might be delays as there is so many people that need the update!!!
I updated mine manually as well. It was pretty darn easy and I think it was pretty fast as well. Definately made a difference. Much smoother and faster. The camera is working really well now for me.
