if Arcsaber 11 going out on March/April 2013, then a new Voltric will be launched on August/September 2013.. just my opinion...haha...like early this year, I had a hunch that Yonex will launched Nanoray 800 and eventually, it's true! :P
Looking at the Japanese HP of Yonex, it would seem that Voltric 30 isn't a high end racket, but rather for novice to intermediate. Besides, the VT-30 is already on sale in Japan (since December) and it comes in a variety of different colors. That would make it a 2012 model and not 2013. The high end Voltric will probably be announced later on.
