Right now, I'd say a few years...I can't really think of an exact number as they seem to be farther than they were after AWE for making the fourth film(as Bruckheimer said that they've been working on P5's story since they were filming OST).

Though I personally wouldn't really guess as of now considering, as far as I know, we don't really know what's going on other than rewrites. All I can say now is that they should be at least close to finish writing at this point.
