Rick - I'm way ahead of ya ! Here is the response I got from Yamaha today:

"Unfortunately, the PSR740 sustain is global, whereas the 9000 sustain is not. We won't have any information on the new stuff until after July 20th, and we haven't even seen any of them yet, so please call us at (714) 522-9000 after July 20th. Thanks."

I assume he misquoted the model number, because i asked him about the 2000 with relation to the 740. More "Hurry up and wait"
