I haven't been able to post for a while, but I AM SO GLAD TOONAMI IS BACK!!!!!
That being said, I really hope they air new shows in the 12:30 and 1:00 slots. I know a lot of people want older Toonami shows and series to sprout up again, but I don't think Toonami should be a nostalgia block. The revival should be used to regenerate interest in the anime industry, airing the best of the best new anime. 2012 is a good year, there's a lot of high quality stuff comming down the pipes and much of it is fresh in tone and atmosphere. So they should focus on getting newer stuff for a new Toonami instead of walllowing in reruns.
Of course, I do think they should get some older stuff, particularly some of the block's shorter but definitive shows, like Outlaw Star, or perhaps even Tenchi Muyo. I think an older show is what will air in the 2am slot, and as long as it isn't Dragonball Z, I think everyone would be happy with just anything they could show there.
As for the newer stuff I'm hoping for, I've been hearing that [adult swim] isn't getting Panty & Stocking with Garterbelt, which is a shame. Aside from Inuyasha: The Final Act, pretty much any new licensed anime could be possible. Personally, though, I'm hoping One Piece makes a comeback, but at this point that's unlikely. I don't think Tiger & Bunny's dub is finished, and I don't really think Naruto Shippuden will be shown either, at least not at this point. Funimation has a lot of good shows that are going to be comming out soon, like Fractale and Shangri-La, that [adult swim] might be interested in. But they've passed up on great shows like Soul Eater and D.Grayman in the past, so I dunno.
Perhaps Black Dynamite will be apart of this new Toonami. The show looks really good art wise, and the plot isn't any sillier than, oh, Bobobo-bobo-bobo or Duel Masters, beloved Toonami shows in the past. It'd be a perfect fit, and remind people that Toonami is not just about anime, it's about airing the finest action cartoons on the planet!
As for the encore slots, I hope those are only temporary and will dissapear as the block starts to (hopefully) expand it's show pool. Six hours is a lot of time, but the way [adult swim] is splitting it, the new Toonami is basically three hours, which is a little short if you ask me, especially for a weekly block.
And as for the talk about a Scott pilgrim animated series, I wonder if they made one, they could make a completely new plot as well. That would be cool.
