Guess I should have stated that I meant the Switch version only and not both versions put together. Hence whi I stated why BotW had to he compared to Twilight Princess as opposed to. Ocarina of Time.
If switch version can hit 10mil alone that would put zelda at at least 12mil lifetime.
Im still going with 10mil but if botw hits lets say close to or even over 8mil by years end, thw game could pull mega huge numbers. Like 15mil lol
