As mentioned earlier, it looks very much like Patch 2.4.2 is going to drop today. Those are the most up to date notes from the PTR

Blizzard has also announced BlizzCon 2008.  There look to be a lot of contests this year, as well as a silent auction.

More Wrath tidbits continue to surface. Things such as mounts that can carry passengers, the Trainers and AH crew staying put and not venturing into the new lands (again), and in another bit sure to stir things up, it seems the devs felt that they didn't reward PvE enough in TBC, (as the focus was heavily on PvP) and will look at adjusting that in WotLK.

Tigole drops a few bombs by announcing that the Zul'Aman Bear Mount will not be available after WotLK hits. They want to maintain the prestige of having done the zone "at an appropriate level". They are also looking at changing some of the titles, such as "Hand of A'Dal" and "Champion of the Naaru".

In a "Rust Storm" style move, Blizzard has taken action against Arena Teams that practiced Win-Trading. Several folks received 72 hour or even permanent bans, while every one caught had their Arena gear stripped off and their Arena Points total reset. Why folks think that they'll get away with cheating is beyond me anyhow, but it's nice to see Blizz crack down on this, as it was making Arena irritating for those not doing it.
