We're all a bit too 'relaxed' in the Gash project, so it'll take a while.
As for the series itself, ep42 aired today in Japan... From the looks of it, it'll continue way past 52 eps, unless they're planning on cutting the anime halfway through the plot. It's still episodic in nature, though new characters get introduced and subplots solved.
BTW, it's based on a manga called Konjiki no Gash!!. It's serialized up to 149 chapters now, with 13 volumes released. Around vol 11 and 12, the manga started a continous, major plot, but the anime isn't up to that point yet.
