estimated timeframe for Ch5 is Sep or october as of last weeks progress update there is 4 days planned day 2 is already 1/2 way done with the renders so I doubt would be next year unless there is some serious delaysChapter 5 is probably a long way off at this point, next year is my estimation. But this game is fabulously written, graphically beautiful and just one of the best VN's I've played.
