Instead of putting all this effort in making something else, than these April's fool jokes...
A "few" million of other people are waiting for your "prolonged" WoD expansion release.
You are speculating on new "classes" in D3, making a really convincing story on Goblins joining the Alliance, talking about some Mortal Kombat style game.
That's a LOT of effort put in, by someone who states that they have their hands full, and making constant progress towards the release.
My thoughts, you don't give a **** about the community, will release when the moment is most opportune for you.
Best regards,
A FINALLY satisfied Diablo player, and a retired WoW player ( for now ).
