Pure speculation about Gin's bankai: (special powers and such) 1. Maybe he can swing his sword around really fast, and create like a sword dome, with everything inside a 13 KM diameter being cut to pieces 0_0 2. Maybe, out of the extended sword, he can grow multiple more swords, that can also extend as far as the original shinso. 3. Maybe he can make his extended sword split, creating multiple sword fragments, that each follow the target, extending in order to be able to catch up to that target (flying extendable heat-seeking missiles). 4. Maybe he can point his sword upwards and stir the skies, and make it rain swords. 5. Maybe, if his sword can cut through the ground, he can create small vulcanoes by slashing downwards. 6. Maybe he can extend and shrink his weapon so quickly, it can become a sword-machine-gun (back-forth-back-forth-back-forth in 0.5 sec or so) 7. Lastly, maybe he can make a sword-cage with his bankai, and everything inside the cage is punctured by multiple shinso-like weapons that extend from the interior of the cage, stabbing through everything inside.

I just hope Tite Kubo won't leave it at this excuse for a bankai.
