I haven't listened to the new voices and for me they're not even "voice changes," because I'm not well acquainted with previously used voices. Beyond Kingdom Hearts, and I didn't even particularly like those.

That said, I find the idea of petitioning to get different voices that have been already cast absurd and reaking of entitlement. If new voices bother you so much it will ruin the game for you then, fine, don't buy it. Don't expect creators to remake their works to your vision just because you and a few bozos got together and wrote your names on something. I'd rather have a turn-based FF7 remake, but I'm not going to try to circulate a petition about it. Square has made their choice. It's already well into development. Expecting them to change it because you make some noise is both naive and entitled. And no, they're not going to record the whole game with a second cast just because you and whoever else signs your petition doesn't like their choice.
