Okay, I've listened to the whole interview and I can say now that this was a little overreaction
As I thought, the team is considering some changes in order to strenghten the symphonic elements in the song. But remember, what people call "pop version" already has those symphonic elements. They are probably boosting them to increase the epicness of the song. However, the final decission is still to be made.
Another important thing: TSO said the current version was released due to Sony's plans. Sony wanted to release it on March 2nd and to be available on iTunes you must send the song about one month before (I didn't know this). Anyway, they've been working on the definitive version of the song since then, not only this week after the official releasement.
I think this is good news. More symphonic and epicness is
