Most games are digital only or the physical discs are somewhat limited anyway (requiring online account or downloads to activate the game in example. Also Capcom doesn't count physical carts on Switch 2 as physical, if they are game key cards. Which is fair I guess, but it makes it inconsistent with other companies numbers. After GTA 6^(1)^ lands and sells millions, they will say "see digital sales are higher than physical" compared to the overall sales of all titles.

for anyone who missed it, GTA 6 will be released as digital code in a box only, which they might count as digital sales, I'm not sure how this will be counted yet
