UPDATE 11/12/14 1.30pm: Square Enix has now officially confirmed the PlayStation 4 version of Final Fantasy 10 / 10-2 HD and given it a UK price.
The pack will be available as both a physical release and digital download in spring 2015, and will cost £34.99.
Square Enix has also given a £12.99 price for its recently-announced PS4 port of Final Fantasy 7 - which will only be a digital download.
ORIGINAL STORY 9/12/14 9.00am: Final Fantasy 10 / 10-2 HD Remaster will release for PlayStation 4.
The page, since pulled but archived by a Google cache, lists the unannounced PS4 version for release in 2015. Oh, and the URL of the pulled Square Enix Boutique page is a bit of a giveaway. And eradicating any further doubt, there's even an image of the PS4 box art.
Final Fantasy 10 / 10-2 HD Remaster launched for PlayStation 3 and PS Vita in Europe in March. Digital Foundry's Final Fantasy 10 / 10-2 HD Remaster Face-Off compares the new versions to the original PlayStation 2 releases.
A Square Enix spokesperson told Eurogamer: "We are looking into this matter and have no comment at this time."
