One argument against a remake is that they would be competing with themselves and their new releases. GNR and Toy Story would have to compete with POTC for sales and assembly line time. The market for JJP games is smaller than that of a stern pro and in some ways they could be their own worst enemy.
But if there is a real chance to make additional $$$ then they should absolutely make it happen. Hopefully they have some insight into what potential sales could be.
