well, I guess half a year for an episode is more realistic a term than the estimated (mentioned by the dev) 3 months.
here is the problem with the VNs: in a best case they can be impressive, but unfortunately, don't possess much in terms of gameplay. it's an engaging, but short story which takes so much developing time that an initial customer could grow cold to that sort of thing. I don't expect from this game to present some sort of tycoon mechanics (though that would be so cool, just what this game needs: a repetitive element like shooting porn with various decorations, plots, costumes etc. something like that old game 'The Movies') in the following updates, but this better be more than just a VN-on-rails game.
