I still can't see where there's a real problem with this. GG are only 1 ep away from finishing, and it will take at least 3 months for us to get to the end of it (more actually since it we wouldn't be able to finish it this year), and, even given GG's track record, I think they'll finish ep13 before we get to it. And even if they don't, then you simply move onto something else and when/if ep13 is released, play it on the following OAV/scary anime night.
And as ARTA8SIMS said earlier, if you go onto a new show such as Seitokai no Ichizon or Kimi ni Todoke and the groups subbing it drop it, then you're in trouble much earlier since there aren't as many eps out yet.
Really, if that's the ONLY reason you're not playing Zan, then I personally can't see a problem at all.
