Yes, they did.
"Microsoft will not make any existing ZeniMax games exclusive to Xbox. They will continue to be available for purchase for PCs and other gaming hardware for which they are currently available, which will ensure that they continue to be available to current players of those games. Microsoft will not be removing players' access to any current games, no matter where they currently play."
"For future ZeniMax games, Microsoft intends to make these games available for purchase on PC and, where the games are designed as native mobile games, on mobile devices running both iOS and Android. Future decisions on whether to distribute ZeniMax games for other consoles will be made on a case-by-case basis, taking into account player demand and sentiment, Microsoft's strategic and financial goals, and the willingness of third-party gaming hardware providers to run Microsoft games and services. Microsoft will make all acquired games and future releases available to subscribers of its Game Pass service on the day the games are launched (which can be used to play on PCs, Xbox consoles and Android mobiles), but does not currently anticipate distributing them through other subscription services. This reflects Microsoft's broader strategy to promote a subscription-based model which it believes will generate value and choice for game players. This policy would not preclude players from downloading or buying these games outside of Xbox Game Pass: Microsoft anticipates that existing games and future multi-platform games will be available for purchase from relevant digital storefronts of all major consoles and PCs."
