The trailer they embed for the release announcement shows them swapping, since like the Diablo remaster, I believe you can realtime toggle the changes on and off.
Thanks, I wasn’t able to view the trailer on safari mobile in private mode (asks to sign it but I don’t have an account). But it worked fine on youtube - https://m.youtube.com/watch?v=_iWMpW_C7Z0 if anyone else needs a link.
