"Our next big launch is on Facebook and we've been working with them for some time," said Gaikai founder Dave Perry at Cloud Gaming Europe while demoing Blizzard's World of Warcraft running in the cloud. "Facebook already owns the category of casual gaming, we're going to help them own core games. A click and boom, you're playing World of Warcraft."
