Blizzard Entertainment released three images as a community reward for pushing the Diablo III Facebook past the 975,000 Likes.
The gameplay screenshot shows the male Wizard casting Wave of Force. However, the usual expanding bubble that knocks back incoming enemies is used against a single massive hulk.
A closer look at how the Wizard manages to be high in the air using this skill seems to suggest a runestone can alter the skill to knock the Wizard upwards instead, as a mechanism to escape deadly attacks.

It's very likely what this new wizard screenshot shows is a variation of the Wave of Force skill never seen before.
