Since 2004, the Warcraft franchise has been fairly centered around the MMO genre. World of Warcraft and its offshoot, World of Warcraft Classic, have been the main focus for the series.
It's been twelve years since a new installment of the Warcraft series from the top-down RTS perspective. Not surprising, of course -- it's long been the accepted and stated wisdom that World of Warcraft provides pretty much all of the Warcraft the company wants. But it turns out that Blizzard isn't quite so dead set on closing that door after all, as Starcraft 2 producer Tim Morten outright stated at Gamescom that the team will be sitting down and discussing the possibility of a Warcraft RTS following the release of Legacy of the Void.
