Well, yes, it's not finished, but unlike many novels out there it has many strong stopping points.
In that manner it's kinda like LoGH.
Hell if it comes down to it, they could simply ignore part 2 and act like part 1 is all there is, and it'd end just fine.
Oh, and I'd love return of 12 Kingdoms and Seikai series, but for FFS... eh.
I've seen nothing but rage reactions concerning the stupid reboot. WTF Nagano, seriously, WTF.
It's like he got tired of actually finishing the series, and decided LOL RESET. Pissed off a lot of Five Star Stories fans.
