Well over on the EU web page they have put a news post saying the EU patch has been delayed for 1 day due to technical glitches with the servers. Don't know if this is something to do with a bug in the patch or just a fault with the EU servers, but given that so far the usual downtime window is nearly up it doesn't look promising for a release on the US servers currently. We can but hope this is just a small delay to make sure the patch it working fully.
