Check this out. I just saw a new Prince EXO3 Tour 100 (18x20) in Dunlop/Prince booth at Thailand Open 2010. The cosmetic reminds me of EXO3 and Ozone. Besides cool cosmetic, this new Prince frame also have boxier beam and thinner EXO3 ports. Even though the frame is not as boxy as Head frames, but it's a good move for Prince to bring back box beam to modern O3 frames. It should hit US market very soon.
