2.4 on PTRs this year
World of Raids is reporting on a recent interview the German site WoWszene got with J. Allen Brack, lead producer for Wrath of the Lich King. While there isn't much in the way of new Wrath-related info in it, there is one bit that makes me happy: they plan on getting patch 2.4 onto PTRs before the year is out, which gives them less than a month and a half.
So far, we don't know a lot of what's coming in 2.4. Here's what we do know:
New area: Sunwell Isle, situated north of Eversong Woods, and featuring:
Improved combat log
We should probably see that trainable Ice Block by 2.4, although it may come sooner
