If it were me, I would give it 2-3 days. If nothing changes by then go ahead and email them asking for an update.
I wish they would just notify us properly. How hard would it be to either add it to the status section or send an email? It would probably reduce the amount of email they get in regard to this issue.
I'm not sure if any businesses were on holiday, but USPS was off. Any orders wouldn't have shipped anyway.
