I've heard this as well, although I have not seen a official confirmation from Capcom on it, merely word of mouth at this point from someone who says that they found out from a employee of capcom (think it was on Capcom Unity).
But if true I would have to say.....why?
I understand updated from the cheesy and very dated dialog of the original Resident Evil game (which I happened to love for its cheesiness lol) but I've played REremake really, and in my honest opinion the voice actors did a great job and it still does not feel dated to me so I just can't see the point if this is actually tru.
