Not sure - the chosen era was not particularly high on my wishlist (I wasn't so keen on gunpowder) - but I am certainly open to be convinved otherwise and the naval battles might be a very interesting addition.
I am likely to buy it if it turns out to be well done but I will probably wait a bit longer than for the previous installments to see how other people here like it.
Of course a new PC will also be required as mine is already 3.5 years old (but I was planning to get a new one next year anyway).
Bottomline: It's not a dream come true for me, but it's not a "no-no" either.
