Sales must be down by a lot.
Digital share on consoles is still far lower than 50%, so it being down 50% physically is quite bad.
Using a 35/65 share between digital and physical and the opening week for WWII in the UK we get:
518k physical
279k digital
physical being down 50% means only 259k sold, so digital needs to be up by 93% in order to match WW2 sales. Doesn't seem very realistic.
