Right, so...it doesn't seem like a second season of the anime is forthcoming. Not anytime soon, at least, and by soon, i mean by the end of this year. I would love to see an OVA adaptation, though (OVA is short for Original Video Animation). Not only would budget be not as much of an issue, the producers wouldn't have to cut or change as much stuff as they would for a second anime season, See here for an explanation of OVA.
I very much hope that somehow, us fans will at least get to see the Hausen House and Krat House arcs animated. :(
