User blog comment:J Fan/Pirates 5 - Sequel News Rundown/@comment-12320611-20130808102109/@comment-1984959-20130809095952

That I understand is why they took Verbinski off Pirates.
 * Actually he was going to do the fourth movie, as noted by the quotes and sources in Verbinski's article. Though ultimately, according to Depp (in one of OST's presskits), Verbinski wasn't able to do it "because of his commitment to Rango."

Again, I have no idea if this will actually affect P5, especially with the so-called "failure" of The Lone Ranger. Now if they had announced the budget some time ago, then I'd be worried...but they haven't. Now assuming The Wrap's article is true, we know 2 things about P5's budget:
 * 1) Negotiations are currently being made for the budget.
 * 2) The budget will be OVER $200 mil, but NOT MORE than $250 mil.

Shouldn't be too huge of a problem, as long as the movie's not AWE scale, which I doubt it is. CotBP-scale budget is definitely out of the question, as sequels are more expensive. Again, according to Box Office Mojo, DMC was $225 mil and OST was $250 mil...so I expect P5 to have the same budget as it's not an original (CotBP) nor a big-scale action flick (AWE).

The only bright side I can give here is that filming hasn't started yet and negotiations for the budget are underway.
