As you can see, discount Trails in the Sky FC will be released to Steam and GOG on 7/29. It will have every feature from the PSP version implemented into it, save for the Monster Manual. But this will be a feature added in at a later date.
That means the battle voices (English VO), New Game+, Retry offset, extra PSP portraits and more are all in the PC version now.

The game will be $19.99, and for its first week, it will be 15% off.
Hatsuu will be posting a blog later that explains all the technical hurdles that had to be undertaken to get this game onto Steam. If you had been seeing anything from XSEED regarding this, there were unexpected issues all over the place, and this is what caused the delay in the first place.
