I think Gin would be the ultimate troll if that turned out to not be his Bankai, especially considering he said "Bankai" in that classic two kanji format. I like that he kept calling Ichigo scary, because it hints at Ichigo not knowing his own strength after his clash with Ulquiorra, something that Unohana commented on on the way to the fake Karakura town. My prediction is Gin cutting off one of Ichigo's arms or something like that, and then Ichigo instantly regenerating without his mask. That would create a moment where both Ichigo and his father would be shocked, and then Gin can call him creepy while Aizen transforms into Yagami Raito. I can already picture the page which shows Aizen's face saying: "Keikaku Doori."

Something that will be interesting (and something not covered yet in Naruto) will be to find out the way the Hachibi resides in Killer Bee. The Kyuubi is locked up real deep in Naruto so and they never talk unless he's within his own consciousness. Does that mean that the Hachibi is just another part of Killer Bee. Since the Hachibi seems so chill we don't know yet if Killer Bee can communicate freely and control the Hachibi or if he has to let the Hachibi take the reigns in order to use that power. This will probably be what he teaches Naruto since whenever Naruto has gone over four-tails crazy the Kyuubi's personality hasn't formed, it's just Naruto being unable to control both his emotions and the Kyuubi's power. But that's what Sage mode is for........wow that was a lot of typing for this short-ass chapter. I think this is comment has more text than that chapter did, just not as much giant squid.
