Here’s an intriguing pre-NAB tease we’ve been cleared to sneek-peak from pages 24-25 of our upcoming Film and Digital Times April 2011 NAB Edition.

Could it be the third Alexa Sibling? The wicked leaked picture sure looks like an optical viewfinder, an ALEXA handle, and an ALEXA wireless control antenna. The rest of the camera will be revealed on April 11, in our NAB Edition and at ARRI’s booth C4337.
