After this exhibition is done there's one week (with one more, final exhibition) left. The game is supposed to end shortly after that point, so you can sort of extrapolate current development time into how long it'll likely take to get the remaining 25% or so done.For anybody... If you had to take an educated guess, how many more development years do you think will pass before TD and Gil reach the point at which they would consider the primary narrative arc of PC as being "complete"?
tl;dr: 2 years or so would be probably reasonable. 5 years * 1.3 ~= 6.5 years, plus margin of error and/or epilogue.
