Araujo on the long time it takes to localize Monster Hunter game…

“No, we don’t enjoy seeing you suffer… Localization is just one of those things that takes time and a lot of strategy. For one, it’s not just translation. Plus, we wanted to deliver a title that had full online multiplayer integration (Wii U), and that took a lot more development. But now we can offer you MH3U on the Wii U, with HD graphics, online, save-sharing with the 3DS version… that’s all awesome stuff – but it all takes time.”

I don't have a sorce for this, a MH facebook page wrote it... Anyway, this is why MH doesn't come to the West very quick.
