Word is that Kane will be on the RAW brand as a heel when he returns. Kane is scheduled to be back before the Royal Rumble pay-per-view.
On a related note, there’s been a lot of speculation on whether or not Kane will be masked when he returns. Word is that that decision is still up in the air. Officials wanted to use the mask in the video so there would be no question that it was for Kane’s return. It’s also interesting that with both Rey Mysterio and Sin Cara out, there is no masked man in WWE right now. As everyone knows by now, masks are a huge seller for WWE.
