I'm pretty excited about it, it's not going to be too long or too short for my tastes. But the Arc before this seemed like just an annoying filler I just hate fillers with a passion, mainly since it had almost nothing to do with the series until the last chapter or so. I know for a fact that they will introduce the Vasto Lorde in this final arc seeing as how they are the strongest of the Hollows. But I got a theory that Ichigo's mother was once a Vasto Lorde and she ended up leaving which is why Grand Fisher was told to go out and kill her. He attacked Ichigo knowing his mother wouldn't attack him full force without killing her son, and because she didn't she was easy to kill. They reference that Ichigo's mother was not killed on accident but rather for a reason. This is what I think though, I love this series and am sad to see it go, but I'd rather it go out while it's still interesting, I have also heard rumors that Grimjow may make an appearance some how in the series in this arc.
