Question about Shadowmourne

Is the Content WOTLK out already?
and if WOTLK is out already is Shadowmourne fixed or not useable in Arena, or will it be when it is out?
on AT you fixed the stats from Shadowmourne and that balanced the Arena, because before that there were only warriors, dks and Palas on the top of the Rankings...

Considering you are talking about Lordaeron realm, all content will be released in due time when it's ready, same goes for Shadowmourne. It's stats won't be modified nor it will be disallowed in arenas, BGs or anywhere else.
