it's great news, and pretty much validates all of us who have spoken out against activisions influence since they joined and the cash shop was introduced to WoW.
That said, even though Mike and the others all are responsible for inviting activision in, harming the product we all love, i dont blame them one bit for taking a payout from activision, i'd say the same to any succesful entrepreneurs whos businesses gets sold for billions (skype, instagram, photobucket and so on).
And now when the dust has settled and hindsight is 20/20, they want to go back to a simpler time, where games weren't about money. I look forward to seeing what the leads of Starcraft and Hearthstone can come up with.
Lord knows the strategy genre needs fresh blood
