My verdict:
I just checked out the samples - go here and click audio:
http://www.rolandus.com/products/productdetails.aspx?ObjectId=825&ParentId=18 I think the Roland has a great LIVE sound which is often missing from Yamaha (including the T2). I especially liked the piano and drums on this machine. Unfortunately Yamaha really has to pick up its socks in these two areas. (You would figure that a keyboard which is kind of an emulation of a piano, would have a whole host of great piano sounds to choose from - but alas this is something all the companies could improve on.)
However, the Yamaha guitars and brass beats the Roland hands down - there not even competition here as you can hear for yourself.
