If GTA 6 isn't delayed then 18-19m seems most likely. I don't think GTA 6 will cause a surge in sales as big as many are expecting due to just how many people will already own a PS5 by the time it releases but it'll still for sure have a big impact the period it releases which combined with the PS5 Pro helping sales and it looking like a huge year for gaming in general will not only soften the decline drastically it'll even give it a chance of ending up somewhat up for the year which would likely be its last strong year.
