I received this reply from Interweave regarding the status of the Cable-Down errata just mere minutes ago....
I think that we have two small corrections for this pattern concerning
the sleeve increases; one that the author used a M1P increase on the
sleeves, and two that the author then knit this increased stitch in the
next round. The corrections have been sent to the web team, and I've
asked that they make posting them the top priority. I don't know
exactly when they will be posted, but I hope that it is very soon for
our readers' sake!
If you have any further questions, please feel free to contact me.
.....I thought everyone here would like to see this - hope that it's not a duplication of info that has already been posted multiple times!
