I agree with the crowd that is fairly "meh" about this trailer. To me it's not as impressive as either of the previous expansion pack trailers (Burning Crusade, or especially Liche King). Not to mention the fact that the whole "uber dragon" thing seems kind of stereotypical, and kind of out of place given that a Dragon, even a big one, seems kind of anti-climactic compared to The Lich King. It also seems like a lot of "writer's fiat" to do what Blizzard wants despite all common sense, I understand Deathwing is supposed to be a big deal, but compared to say The Lich King, Yog Saron, or Agalon he's small potatoes.
Oh, I'll doubtlessly play it for a while, at least until "Old Republic Online" comes out, but to me they should have just had a giant celestrial chain with a wrecking ball made out of a giant money bag knock everything over. That would summarize the point of this expansion far better than this cinematic would.
I'm one of the vocal minority that feels that the proper course probably would have been for Blizzard to give "World Of Warcraft" a decent send off, and then release "World Of Warcraft 2" sometime down the line after their upcoming new MMORPG. Be classy and pretty much stop taking subscriptions and end the game while they are ahead, rather than stretching everything out to drag every possible penny out of the thing until it's left as nothing but a withered, exploited husk, that even the last remaining fans can't appreciate very much when it finally hacks out it's last rasping gasp.
It's stuff like this that has me complaining about the corperate mentality, and how properties are made to suffer. I'll also be blunt in saying that Blizzard has so much stuff on it's table that I think they should be a lot more focused, and taking WoW off the table for a while while it's still thought of fondly, would let them invest those resources in their other projects.
This is just my thoughts and opinions though. Understand that I'm a long time WoW player. I've been an RPer (I play on an RP server), a PVPer, an ultra Hard Core raider (second guild to down Illidan on my server), a casual raider (now when I'm semi-retired), and everything in between. There is a point at which I have to say "give it a rest for a while". I mean cripes dude, we just took down a primal force of nature (The Lich King as the lord of the dead), a cross between a Lovecraftian elder god and Marvel's Nightmare (Yog Saron), and a version of Galactus known as Agalon who was sent to blow up the planet to prevent the escape of said lovecraftian terror by this universe's equivilent to The Forgotten Realm's "Lord Ao"...
Keeping this going and progressing in the levels is just going to get continually more retarded, and no... despite all the hype Deathwing is a pretty lame "next step". I mean cripes dude, we had a lesser boss that was right out of "Might and Magic"... a Bolo-like AI tank controlling orbital satellite based weapons!
