Looking at the release dates of the previous models.. will we have to wait till mid 2012 ?
Looking at the press release dates of previous models quoted on psrtutorial.com =>
http://psrtutorial.com/sty/yamaha/index.htmlTyros 2 Press Release Date: Nov, 2005
PSR S500 Press Release Date: Oct, 2006
PSR S900 Press Release Date: Jul, 2007
So going by the above timing we would have:
Tyros 4 Press Release Date: Oct, 2010
PSR S650 Press Release Date: Around Aug, 2011
Mid Range Model : July 2012 ?

or Jan 2012 ?... not far away
