Unfortunately the issue is that the series has already gone through rewrites. I think the essence of the main story needs to be boiled down to get those main points across and the filler excised if the series is ever to finish. I can see it being done in 2 games but that also supposes that Suzuki has the opportunity to make both of those games and that the budget for each is sufficient enough to get through the requisite chapters at a basic level.
Given the nature of the series and its constant compromises there's a chance that won't happen. If that's the case I would prefer a written ending for closure than just trying to dump it all into S4, but that's just my preference.
