Ok, did some digging, and thought I should clarify a few things the best I can. Anyway, looking at the original Variety article aka the source of the latest Pirates 5 news... As far as I can tell, Jeff Nathanson is likely a part of P5 - taken because these types of news tend to be accurate, especially if it's all over the web. However ...I wish to make clear that, as far as it should be know, that doesn't mean Terry Rossio isn't still involved - note how nothing said that Terry was out. Plus the fact of a statement made by Comingsoon.net): It's unclear whether or not Nathanson will be working from Rossio's draft or if he'll be tackling the project as a page one rewrite.

So it's safe to say that for now(unless if it's confirmed that Terry's out; which I truly doubt it), I'm pretty sure that Nathanson is only helping out with the script. Bear in mind, P5 is literally the first Pirates film to not have Terry writing with Ted Elliott, who has left many moons ago.

In short ...as far as it should be know, Jeff Nathanson is now part of P5 but Terry Rossio's involvement or leaving has yet to be officially stated. We should have a clearer message soon, but one can only hope.
