Although it might feel great to Yamaha fans, it's always a good thing to have competition...it forces companies to keep up" and we, the user, always benefit.
Losing Roland isn't a good thing, in my view...it was Roland, with their E-20, that forced Yamaha and Korg into improving their arrangers.
Also, there's one less choice...not everyone likes Yamaha's smooth CD-like sound...Roland had a more "live" sound that was appreciated by many players.
I hope they re-enter the market, although the prognosis doesn't look good.
I'm still waiting for my Tyros4...hopefully it will arrive before the Tyros5 introduction.
