Tyros 2 is not just a software update, it is a major hardware update as well, in fact if you have a close look at the chipsets used you will find hardly anything that relates to the Tyros 1.
As for getting Yamaha to listen outside of Japan, please bear in mind that there was heavy involvement from the UK on Tyros 2, (Both operational and voicing) which proves that Yamaha will listen, if you have something to say.
