What you are saying is impossible, no way Jose, no new expansion this year. They didn't even start closed beta dude, do you know how releasing expansions works? For Warlords closed beta started somewhere around march 2014, with release being in 17th of november 2014, that's 8 months of beta & testing. Hellfire Citadel is still a new raid, and you have to kill Archimonde 20 times (weeks) to fully upgrade your ring, so forget about it rofl.
Summer of 2016 is earliest I can think of for the new expansion release, that's almost a year, and most likely it will happen like that to release it at same time with the Warcraft movie. Warlords has a long way ahead before it ends.
And no, not everyone hates WoD, only the ones who aren't active raiders in a raiding guild, indeed, there's not much to do in WoD except raiding, but the raids are awesome.
