Final Fantasy 15 might be coming to PC.
The site code was discovered by NeoGAF user KupoNut, and has since been removed. As you're about to see below, it makes references to PC and Windows 10 SKUs.
Other references in the code mention a number of new pages that will be added later, such as a trailer, FAQ, an about page etc. However, it's worth noting that this code is almost identical to that found on the Rise of the Tomb Raider page, and Square Enix could've just copied it from there despite not planning a PC version.
Whatever the case maybe, the Uncovered event is due at the end of March, and lots of exciting announcements are expected.
