The latest confirmation comes from Vivendi, Blizzard Entertainment's parent company which announced they have plans for converting all their game franchises to MMO, including Diablo.
-Humankind cannot gain anything without first giving something in return. To obtain, something of equal value must be lost. That is alchemy's First Law of Equivalent Exchange. In those days, we really believed that to be the world's one, and only, truth.
its based on the missunderstanding we've already seen. The Vivendi gaming section with the Blizzard gaming section didnt communicate that well, apparently and that statement came out. Nothing new here.
I hope this is wiki being wrong again.
