Sorry Guys. It seems I "may" have hooked up to the Yamaha site whihc referred to the Tyros "3". But it had me in a panic.
Here's the link for what I saw:
http://usa.yamaha.com/products/musical-instruments/keyboards/arranger_workstations/tyros/?mode=modelWhat caught my eye the most were the words "Tyros" and "Discontinued".
I sent an email to Yamaha about it, and they replied back that the Tyros 4 was a "current" model.
My Bad......
