I fully agree with Denti's post. Airbus-style sidesticks, just interconnected, would be fantastic. Have seen a demo sidestick on some airshow by an airbus supplier years ago (must have been ILA08). They could even emulate stall buffet and other "feelings" on their connected sidesticks. Most impressive. That should be the way to go for the Airbus NGSA A320-follow on or however they call it. Current sticks are responsive but can feel a tad "dead" if you have seen the difference.
And I'd personally dislike any fixed F-16-style sticks. However for a high g environment they might just be best fitting. Different business.
Finally the keyboard will be the most used interface during any flight. Moving the yoke out of the center seems just logical.
