They did announce the next gen MMO, World of Jersey Shorecraft...

I think it was a weird time for blizzard, they have a game that everyone knows a ton about thats all but finished, and they recently released another game, so they didn't want to overshadow those games with anything else. It was disappointing, but not unexpected. They said they wouldn't even announce the name of the next gen MMO until 2012...

Oh, and watching SC2 or WC3 tournament is WAY more interesting than watching Wow tournament.... the wow tournament just showcased how ridiculous arena pvp is, with everyone getting healed to full in a split second, and nothing much happening.
