First new IP in 17 years? Hearthstone was announced about a year back...

Do you consider that a new IP considering the full title is "Hearthstone: Heroes of Warcraft"?

Because if so, you might as well count World of Warcraft as a new IP too.  I don't.

I do count WoW, Hearthstone and Heroes of the Storm all as new IPs. Blizzard seems to employ the Nintendo model: make new IPs with existing characters/universes.
