YEah I could keep waiting on the corner for the next bus or I can get on one and actually go somewhere.

I believe Roland is behind the curve in this genre and way ahead of the curve in the Hip Hop dance stuff, That is their main focus in my opinion. Home keyboards are an afterthought,

Yamaha is all about home keyboards. That said I do not see the Tyros 3 being light years ahead of the Tyros 2. Why? Because their $7000 Clavinova which just came out is not that much different. The S900 is not a huge leap above the PSR3000. The Yamaha's best features is the worldwide support.

Korg has been at the leading edge in synths for awhile starting with the M1, then the Triton series......I think the Fantom will overtake the lead in the workstation area,

However on the arranger front I believe they are closest to a workstation with an arranger then Yamaha. The G70 would have to make a HUGE leap for me to want to go there. I don't see it happening with Rolands' foucus on the FAntom and their propensity for hip hop and that genre of music.
