Square Enix has revealed pre-order bonuses for the Final Fantasy Pixel Remaster titles, which includes special OSTs. Other pre-order bonuses include exclusive wallpapers consumers can download. However, these bonuses are only available when pre-ordering the PC versions of the games. Additionally, the Final Fantasy Pixel Remaster OST pre-order bonus will only be available to download. The mentioned wallpapers will work similarly. [Thanks, 4Gamer!]
Each Final Fantasy Pixel Remaster OST will come with a total of three songs. Each track features the original version of the song and will gradually progress into the new, re-arranged versions of the tracks. Additionally, the OST is not available to purchase separately from the individual games. As mentioned previously, consumers will also receive wallpapers with their pre-orders. A total of two wallpapers will be available per game.
Square Enix recently released a Q&A page for Final Fantasy Pixel Remaster. This included information about notable members from previous Final Fantasy titles contributing to these releases. This includes artist Kazuko Shibuya and former series composer Nobuo Uematsu. Square Enix also mentioned that with enough interest, it would consider bringing these titles to other platforms.
