UPDATE: The listing has been removed as of 05/04/2017.
While Rockstar Games has never announced a PC version of Red Dead Redemption 2, BestBuy.com may have not gotten that memo. Appearing today (and likely not for long) is a listing for Red Dead Redemption 2 on Windows. I have included screenshots below of the listing.
The listing uses generic “Featured at E3” box-art, and only has “Just Announced at E3. Stay tuned for additional information.” under Product Features. No release date is available either. While I expect this listing is a mistake, let’s hope the PC version it predicts is not.
