For people who don't need all the features and just want to shoot HD, Arri have brought out a basic version of the Alexa.

Introducing the Arri ALEXA HD | CineTechnica (http://blog.abelcine.com/2013/07/01/introducing-the-arri-alexa-hd/)

Abelcine is selling the body for $44,000.

I wonder if this is in response to the F55? They're getting closer in price. No 4K for this camera, though, should you need it.
