Arri is not talking about anything beyond 60fps at this time, note the cameras only been shipping for 3 weeks or so I would expect to see higher frame rates on the later camera versions, the first one was designed as more of a utility camera with the later models offering Optical viewfinders (no lag) and more advanced processing later on. I expect to see those updates at least announced by NAB next year.
Red made a big splash with filmmakers trying to be there best, with Alexa, I am seeing the guy, really big guys at this, that said they would never embrace digital actually coming around to touch the cameras and have a look see.
