I guess so far the only evidence of the RX-71 is the keymapping and all the talk about the "lead device RX-51"? Anyway, I'm thinking that if the RX-71 exists and there are plans to release it, it will be confirmed at some level when the Rover is released. Something like - "one more thing, there's also this larger tablet model coming out soon after the Rover". I find it hard to believe that they would release it a few months after Rover without a word at the Rover release. What do you think?
