We can read there from the blue post:
http://eu.battle.net/wow/en/forum/topic/2868766264.08/11/2011 17:20Posted by UlvarethWith the release of the next World of Warcraft content update, Hour of Twilight (patch 4.3), players on European realms will be able to play World of Warcraft in Brazilian Portuguese. On December 7 a realm dedicated to the Portuguese community will open with optional time-limited free character transfers from specific European English realms with high Portuguese populations. Please stay tuned to these forums for additional information.
2 weeks as passed since this thread was created and we are now less than 2 weeks away from the incoming server and still many questions have been left unanswered.
Some answers have been given in this thread!
And about the info we got about the Realm being a PVE one, most Portuguese ppl are in PVP servers. This should really be reconsidered.
