Secret of Mana remake announced!

But wasn't the 'missing content' from Secret of Mana re-worked and used to develop Chrono Trigger? I thought I remember reading that at the beginning stages they were the same game, and ended up branching off into two different projects after the CD system revoke? I wanna say that Hiromichi Tanaka mentioned this in one of the Secret of Mana supplement books. As far as I know, the only content that was left out, was some dialogue instances in the US release because of font space restrictions. ...but I could also be wrong. Hopefully, if there is some planned content that wasn't able to make it into the original release, SE will add it back in for the re-make! More Mana story sounds awesome!
