Hmm, that does raise the question then: is this a 'the order has been sent to the printers' reprinting, or a 'we all think it's a good idea to do sometime soon' reprinting?
It means the errata has to be collecting, the files edited, reviewed, approved, sent to printer, check work from printer, printed, shipped and distributed, etc.
It's in the process, but I don't know how long that process will take.
It is being reprinted.
