Core decision: MW4 is confirmed for October 23, 2026 on PS5, Xbox Series X|S, PC (Steam / Battle.net / Xbox on PC), and Switch 2. There is no PS4 or Xbox One version, and no Game Pass at launch. The choice that actually matters is where to buy so you get campaign early access (Oct 16), avoid last-gen dead ends, and do not overpay.

1Platform Comparison

Best visuals plus campaign week early
PS5 / Xbox Series X|S / PC (Digital)
Digital pre-order unlocks Campaign Early Access starting October 16. Physical copies do not. Pick this if you want the campaign a week before everyone else.
Xbox household, play on both console and PC
Xbox Play Anywhere
Buy on Series X|S store or Xbox on PC. One purchase covers both console and PC. Not last-gen. Not Game Pass day one.
Switch 2 only or handheld
Switch 2
Portable plus gyro and Joy-Con 2 mouse mode. Expect lower resolution docked. Beta consensus: runs ~60 fps in MP, looks softer, handheld hides it better. Retail is code-in-a-box, not a game card.
Still on PS4 or Xbox One
No MW4 for you
There is no last-gen version. Warzone on those consoles also ends when Season 1 hits after launch. Do not wait for a port that is not coming.
Key decision: if campaign week-early is the goal, buy digital only. If you only care about discs and do not mind waiting until the 23rd, physical PS5 or Xbox is fine. Switch 2 physical is a code, not a cartridge.

2Exact Pre-Order Steps

Beta is over. Early access ran Aug 21-25 for pre-orders, open beta Aug 28-Sep 1. You cannot use Game Pass to sneak into a leftover beta.
