Looks like Odyssey will win easily.
I mean if we're talking about which will win the inaccurate pre-order charts sure. CoD being the actual sales winner is essentially confirmed already.
Mario Odyssey - 1.1m (first 5 days in USA, retail + digital).
Call of Duty WW2 > 1.4m (Likely well over as this figure is doubling the retail copies of IW's USA launch only, and it's the best selling digital launch on PS4 ever.) - (selling twice as many units in its opening weekend as last year, and setting the day one record for full-game downloads on PlayStation 4.)
