Since today's first question in Maelstrom-themed, we've decided today's edition of The Queue was a good time to link the supposed leaked trailer of the upcoming World of Warcraft expansion, to be announced at BlizzCon '09. We haven't embedded the video to try and dodge waking up to a DMCA tomorrow, so just check it out on YouTube. We'll let Google deal with the mess, eh?
"What instances would you suggest for a Maelstrom expansion?"
All of the things you suggested yesterday would work pretty well. Nazjatar and the Tomb of Sargeras would definitely be raid zones in a future expansion. I suspect we would also have a hella fun time in The Eye of the Maelstrom, which is the center of the whole storm there. Maybe we'd even visit Mak'aru, which is where all the gross crab people live. It probably wouldn't be a raid, but I could see a 5-man there. That is, if we don't ally with the gross crabfolk. Did I mention they're gross? Gross. I'd also lay down money that we'll get an Onyxia/Gruul/Malygos-style raid with a sea monster of some sort. The Lurker Below v2.0, now with eye lasers?
