What we've got here...

...is failure to communicate.

Currently seen as a patch note for the Test Server, no word from SOE on the following:

 - The Hardcore Heritage events in Nagafen's Lair and Castle Mistmoore have been extended by one week. They now end on Monday, September 30th.
- Giants, Giants, Giants and Dragons, Dragons, Dragons return! They will be available from September 27th, 2013 to October 28th, 2013.

So we don't know for sure if this is going live or not.
