There has been a lot of speculation as to whether the Vita would get physical releases of the two remastered games, or whether they would be released digitally only. Well it looks like SE have come to a fair compromise and decided to release FFXHD at retail with a download code voucher for FFX-2HD included in the box.
Here's Lee Williams, SE community manager via the EU PS Blog:
Hey folks! We know you’ve been eager for an update on the PlayStation Vita version of Final Fantasy X/X-2HD Remaster, so we just wanted to let you know that the game will be out in European and PAL regions on 21st March, 2014!
So it’s released on the same day as the PlayStation 3 version; PlayStation Vita owners can get both games in one package, with Final Fantasy X HD Remaster on the PlayStation Vita gamecard and Final Fantasy X-2 HD Remaster accessible via a redeemable download code (inside the box) to be used on the PlayStation Store.
The games will cost £29.99/€39.99/$39.99 at retail or via the PSN Store. This price includes both titles.
