Sorry but I don't exactly know what you mean with the 18m units sold. My last post here regarding xbox . I think and its highly likely xbox will sell at least 35m before GTA 6 releases end of 2025. Will sell at least another 5m in 2026 because of GTA 6 so that's how I think it should easily sell more than 40m lifetime. I'm thinking around 45m if next xbox come out in 2027 but yeah there's just no way it could sell less than 40m. 10m GTA 6 out of 40m xbox series that's 25% attach rate which is similar to GTA 5 on 360
