Square Enix has revealed that the Final Fantasy IV: Complete Collection will be releasing this spring on PlayStation Portable in Europe. In North America, Amazon have given it a prospective date of April the 19th.
The package will include the original Final Fantasy IV, which first appeared on the SNES. However, it will also include Final Fantasy IV: The After Years, which appeared more recently on Japanese mobile phones.
There's also some lovely art by Yoshitaka Amano squeezed into the package to make it even more appealing.
