(I don't think it was quite at the same level as DBZ:Abridged... but this was just the first episode so it'll hopefully improve.) I can't wait to see what they do with the next episode.
The thing is that this is done by another person (TehExorcist) rather than KaiserNeko. So it's not putting much extra strain on KaiserNeko nor is it taking away from his DBZ: Abridged work.
The only thing if TehExorcist started doing DBZ:Abridged episodes is that it might be hard to co-ordinate. So that they keep the same consistent style and jokes without completely overlapping or taking things in different directions. And I don't know if KaiserNeko would want to hand DBZ:A off (even partially) to someone else either.
Personally, if they were going to do any other series, I'd love for them to make a Bleach Abridged. I think they could make that pretty funny.
That's the one I want to see most right now. (If you haven't seen episode 4 yet, I'd highly recommend watching it. So many good moments. "You obviously haven't seen what I've done to the statue of big J")
No idea when the next DBZ:Abridged will be out though.
And for AoT abridged, I think there is a lot of room to make fun of it because the show took itself extremely seriously. And at times it was bordering on absurd. (Especially Erin's behaviour at times.) That and Team Four Star are pretty good at finding ways to inject humour.
