If they show a cliffhanger of Tsubasa vs. Hibiki, I expect a Tsubasa vs. Hibiki fight. Even if Genjurou ends up stopping it, as long as they fought for some amount of time it would have been good. My interest was finally piqued when we actually got to see Hibiki go berserk, but then, as commented, she doesn't even remember AND it only lasts for like 10 seconds.
Then there's the completely unnecessary politics element ("zomg, other countries want our tech! International crisis!") and the poorly balanced school elements vs. fighting (after Code Geass, it's really hard to find another show that does it well; I REALLY don't care that she's behind on her homework).
Even the "twist" at the end feels lackluster since they've been spending so much time on the conflict between Tsubasa and Hibiki that "A challenger has appeared!" will just force them to work together and skip past the forced confrontation i.e. we probably get to see Hibiki being a moron and Tsubasa being woe-is-me for another 3 episodes.
