Below are some extracted pictures from Shimano Japan website of the launch at the tackle show in Japan. For more information of the new reels, its available here and the translated version here. Shimano also launched for Twinpower, Super Aero Kisu Special Mg, Ultegra Searea, Super Aero and Hyper Aero SpinJoy product line for year 2008. However the newly launched Stella SW's pricetag is still pretty high for the moment.
Hopefully they do launch the FA version of the SW like the previous models so its more affordable.
