i guess that's possible, but you can't really make a good copy just from some pictures posted in the forum. i'm sure they actually go out and buy an original before making a copy.
Why is central sports calling the new arc saber the arc saber fire? http://www.centralsports.co.uk/shop.php?page=home
From your sources you say Arc Saber Fire. Then I guess the other version is not fire. Again its only based on your findings.
What if it's NOT a piece of carbon graphite? maybe yonex decided to go crazy and make it out of THIN AIR! A racket made from ultracompressed air...actually no that's a bad idea, air is heavy.
To add to that, I also see some new racquets in the chart, NS4500 and Mp30. ArcSaber10 seems to be a little bit more head-heavier than the Arc7, but seems to be a defensive racquet.
What the ? I can view them all without any problems.. maybe I'll print-screen it and post it. Anyway, here they are, I uploaded them onto photobucket.
