I don't get it... Why hasn't Yamaha updated the VH? Clearly there have been many who aren't pleased with it and have been asking or suggesting that the units VH system be upgraded.

Maybe it's me, but I see the step up from the Tyros2 to the Tyros3..., as the same step up from the PSR-2000 to the PSR-2100. Just not enough upgrades to make the jump with it IMO.
