I don't quite get that, Dennis... why would a touch screen make any difference to updates? It IS still a screen, not a physical panel layout, so the buttons that surround the screen can be as easily re-tasked to do new functions as a touch screen can (or almost!).
And re. the bender... I don't mind whether it is wheels or joysticks or levers. I can pretty much make any of them work. It's the LOCATION that I can't handle. Even a Roland lever, in the position that Ketron use would probably be awkward for me, whereas wheels, where Roland puts the lever, present no problems.
Perhaps it is just an effort to reduce the size of the case (it's not THAT much wider than a T3!) and keep the weight down, in the assumption that most arranger players are WAY too busy playing the chords with their LH to need to use the bender all that much

But then they go and stick a bunch of SMF and MP3 players on them... Oops!
