There's some precedent for parts of this: I am aware of two games (Ultima 6 SNES and Chrono Trigger PSX) where, in the English version, Japanese is swapped out on the fly for English text; in both cases, this slows things down. I also remember reading about some indie game where the English text is the result of machine translation. So, the logical conclusion is that, maybe, some developer might get the idea of having the game translate itself on the fly.
The company's rationale for this strange (and rather silly) approach is that it insures that consumers "will always have an up-to-date translation".
I really see no reason why it would have to be simultaneous with the gameplay, unless there's some very dynamic content which is somehow randomized during the gameplay.
