Bleach's Last Arc and What I want to Know

So apparently the new arc of Bleach will be the last. =(
side note: In case you want to know, Yoruichi watches the anime, and I read the manga
       Anyway, although I know that theoretically an arc could probably take several years, this still makes me really sad. Okay, granted, the last arc was not my favorite, but I still cannot imagine having no more Bleach every week. I've already had to mourn for Chuck (yes, I am a Chuck fan), but Bleach too? While I can appreciate that it's best to end something before it really just becomes a hassle to read and has no more excitement and life, I've always found Bleach at least somewhat entertaining, even at it's worst. I have great memories associated with Bleach, and maybe I've become a little too attached, but what can I say, I don't want to say goodbye. Even if I am a little premature in thinking about this since there is probably still a ton left. 

So in honor of the start of the last arc, I'm listing a couple things that I really want to find out. 
Note: there are a few spoilers if you read on.

1. What happened to Nel? I mean we see her turn back into kid Nel, and she was of course saved, but then what? I hate to think that that is the last time we will see Nel. Not to mention how sad Nel would be if she never saw Ichigo again. And there's also Dondochaka and Pesche

 

2. What about Ichigo's dad? Okay, so Ichigo's dad mentioned that Ichigo would probably have a ton of questions, and then Ichigo said that he would wait for the answers because his dad probably had a good reason not to tell him. So is he eventually going to tell him? Come on, I've been waiting since Ichigo's dad first killed Grand Fisher! 

3. What about the relationship between Isshin and Ishida's dad? 

4. The vizard. What happened to them?! I mean they show up briefly at the very end of the fullbring thing (at least I thought that was them) but no information is given. So what was up with that? 

5. Exactly what powers does Ichigo have right now? (okay, this is kind of tacked on cause I couldn't think of anything else off the top of my head.) I'm sure this will show up rather quickly, but ever since the fullbring thing I've been confused on whether or not Ichigo has shinigami, fullbring, or vizard powers or all three. 

 So that's it for now. I'll probably think of several other things later. And again, the picture policy from other posts applies. Feel free to comment any of your ideas...
