Although I like the improvements on the T2....Let me add to my previous list just in case Yamaha is reading for future units

No More Sharp corners on body

Link MFD to Registration with transpose also

Add separate controlled addition Mic input

XLR Mic inputs

Ability to Play Arranger/SMF/WAV/Mp3 at the same time with separate slider controls.

Use high quality tacky rubber coated knobs & sliders, wheels, for better grip also paint wont peel off.

USB 2.0

Increase Flash memory size
