Its the next expansions name. Cataclysm was/is a battlegroup. Also would tie in nicely for blizz with them announcing the next expansion at Blizzcon, and it ties into whatever shitty lore metzen has shat out of his braincell regarding the maelstrom and surrounds. Lore(lol)wise, the great sundering is also known as the Cataclysm. Blizzard always planned to add Queen Azshara at somepoint (the untextured temple was included with the Vanilla files) and she, as has been said, pretty much one of the last top dogs after Arthas gets owned. Sargeras' Tomb is also in the Maelstrom.
Their next MMO is one rumoured to be using an already existing property of theirs - most likely starcraft, as diablo doesnt lend itself well to massive mo, just mo
Its also where all the actually talented people from the wow teams that worked on vanilla and tbc went, this explains why the content has apparently gotten easier (the intelligent designers have moved on)and any bunch of monkeys can now type shakespeares collected works
With Blizzcon round the corner, I seriously doubt they are announcing a 3rd massive project for themselves (given how blizz really like to announce when shits nearly ready, not a pipe dream); either they are about to announce their next MMO, despite the WoW guys only moving over recently, which means Blizz would have three major projects in development (D3, SC2, and this new MMO), with various years of work ahead for each, and WoW's 3rd expansion wouldn't be announced until another 12 months from now (and thus not releasing until 2011); or It is just the next WoW expansion, launching somewhere between May & September of next year.
However, its a one word expansion name, and going on their previous form for wow, that may not be a trend they want to break.
