Yes, the curiosity on the Pearl having one or two wheels is confusing. Some say flashbacks of the Wicked Wench (obviously unconfirmed but possible), though one could also say it's a mistake made by someone involved in the set's construction. Until we know for sure what's going on, as said before, we can only speculate until 2017.

''Last time we saw the Sunset was in 2013/2014 in Fajardo, Puerto Rico. Are they going to film there too or only in Australia?''
 * Truthfully, I'm more concerned about where the Sunset is. No one's seen hide nor hair of it since Ronning/Sanberg were aboard her in 2013. What the heck?! Oh well, at least they seem to be using the ship's design while making both the QAR and the Pearl.
 * And while it was previously reported that Puerto Rico (and New Orleans) would be filming locations, it appears to be outdated as of the news of P5 filming in Australia. Same with the question of London/Los Angeles (though don't recall too much talk there)...but hey, who knows? We didn't find out about Puerto Rico until August/September 2010. We'll have to see how it goes. ;)
