Is this just Yamaha's typical past practice (again?) of continously promising US delivery and then repeatedly moving back the date again and again (and again)?

Just two days ago, I heard from an official Yamaha dealer that the first shipment of Tyros into the US was due to arrive on November 14th, now I got word from them that Yamaha (last minute) changed the date to January 10th, 2003. Steve, What's the REAL story here?
