I believe the playtest is supposed to end at the end of the month. If Paizo wants feedback on changes they'll either have to relaease them this week or extend the playtest or both.
Right. The playtest is scheduled to run through the end of January, so I would not expect an update from them on the classes til at least the middle of February or even the beginning of March. After all, the APG does not even come out til August, so we should be happy they give us an update at all before then.
