I had three items on pre-order for the November 1st release date, but Ratchet is the only one that didn't get charged or shipped... and still says an arrival date of November 2nd to 3rd... which will be an amazing feat if they manage to pull that off.
It is strange that they haven't sent a delay email, or updated the order to reflect more realistic dates.
Maybe they ran out and haven't decided what to do yet.
