Final Fantasy 7 will be coming to PlayStation 4 winter 2015. However, the holiday release date relates to the PC port of the original PlayStation game, not the remake Square Enix announced at E3.
Square Enix prices Final Fantasy 7 at $15.99 on their website. A list of features for the PC version includes new achievements, the ability to save your game anywhere via cloud technology, and the character booster. This last feature allows gamers to significantly increase their HP and gil to eliminate some of the grind. Whether or not these additions will be incorporated in the PS4 edition is still unknown.
Although it is not the remake everyone is waiting for, this port should be enough to hold over fans until Final Fantasy 7 is reimagined in high definition in 2017.
