9U1-R650-WW00 Discontinued?

[JWW2009]

I was told the World Wide model of the Unleashed R650 was discontinued and replaced with the NC.  Couple of quick questions.

1) Is the Unleashed R650 that old already that it's being discontinued?

2) Is the NC just the USA version of the WW.  (Not familiar with NC).  

3) If the NC is the USA version, can it create a wireless mesh with WW models.  The WW models could possibly use frequencies the USA version doesn't support.  

Thanks in advanced.

USA model numbers end in "US00" as far as I know.  Ex:

901-R650-US00
9U1-R650-US00

I can't answer your other questions, so hope others know.  And I hope it's not too old -- I just bought one haha.  But typically, Ruckus does an excellent job with giving lots of advance notice for End of Sale, End of Life, End of Support.
