UPDATE: I was just informed by Yamaha USA product support tech (Martin) that Mark Anderson (head of Yamaha USA keyboard sales) has now been made aware of new Yamaha Tyros TRS-H1 "Brackets Plates", and that Yamaha USA will do what they can to make them available from Yamaha USA. Martin advised me that either he or Mark Anderson will get back to me (within 2 weeks) to update the availability situation. Let's keep our finger's crossed. - Scott
