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!
Ahhh I see, would it be possible for a Voltric that surpasses the Z-force? Lols, this sounds crazy, perhaps a Voltric i-Force? :OOO
http://www.yonex.co.jp/sp/products/badracquet/voltric30.html 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.
UPDATE** though the specs and the engraving on the racquet say 4U, the racquet definitely feels like a 3U or even 2U. HEAVY! Not just the balance, but the whole racquet is heavy. Generates great power, but lacks in defense and is slow.
