I believe that is the case if you updated to the resent firmware. I believe it does ask you if you want to participate or not in the online backup crap. That's the major concern for everyone. Could it have nabbed your keys whether you agreed or not, possibly.
I also think for those that do not update firmware they are fine in that current state. Those that updated may or may not be fine. Those that chose the online key backup, did you really think that was a good idea?
Those that uploaded their keys, I wouldn't think a new wallet would help.
I'm nobody but thinking out loud.
