I'm not certain of that at all. That's exactly what they did with the 2K, and of course most people couldn't, or didn't want to, part with their keyboards for a couple of weeks. Also, it said almost EXACTLY the same thing on the website about the OS. It was not true, as we know.
According to Scott, even Steve from Yamaha isn't certain how the upgrades will be handled yet. He is certainly more believeable that their web site.
There are STILL ads at internet music stores that claim the 2000 has Flash Rom upgrade capability.
Bottom Line is: To me it is ESSENTIAL to try this keyboard (or any of them really) personally before I buy. And I will most certainly buy something before the end of the year for tax purposes. I don't believe I will be able to see the Tyros before 2003. Hope I'm wrong. My dealer has one on order.
