Well this post will probably only expand the notion of my "nuttiness"; I don't believe the storm stuff has anything to do with the next expansion. That includes the story of the green dragon traveling west of Kalimdor. I believe that's all a red herring because there's simply too much "storm" stuff in 10.2 and Blizzard has never dumped that level of next expansion stuff into a patch in a previous expansion. That level of telegraphing makes it simply too easy.
Nah, I think something else is afoot. I have a sinking suspicion that in a future patch we're going to the land west of Kalimdor, and the next expansion is something else entirely. Probably element based because I believe the Algarian Stormrider is still an elemental, but I'm simply not buying the notion that we're doing another lost continent like Dragon Isles. I do believe that we are in fact going underground as Toweliee hinted towards and Zaralek Caverns suggested. I do believe that Khaz Algar is a place we visit later in the expansion, but it won't be the main location.
So in short, I believe all this storm stuff and lands west of Kalimdor and gryphon junk is all stuff related to the current expansion. We'll see soon enough how correct I am, or how wrong I am.
