The contents of the International Red and Blue were based on the Japanese Red and Green, with all the bug fixes and graphic updates of the Japanese Blue. So, our Blue version was remade, the remake is LeafGreen.
And since the Japanese Blue was a bugfix release, it's existence is moot for the purpose of remakes. In other words, there will most likely not be another Kanto region remake.
