How the Console Race table is built.

1. Primary metric: lifetime hardware unit sales

Console Race focuses on cumulative worldwide hardware unit sales. It does not track revenue, profit, monthly active users, or subscriptions.

4. Generation labels are editorial, not official

Generation labels are used to make the table easier to read. They are editorial groupings, not official categories from the platform holders.

5. Source hierarchy

Official investor-relations and business-data pages come first. If a company stops publishing a comparable total, the site uses a named secondary source or a labeled estimate.

For readability, the table normalizes displayed totals to one decimal place. When a source only says "more than" a rounded milestone, such as Sony's legacy PlayStation entries, the site may display a floor marker like 117.0 M rather than claim that the publisher disclosed a more precise decimal figure.

6. How estimate rows are handled

Xbox rows are the main example. Microsoft does not publish a comparable lifetime-sales page, so some Xbox figures are labeled as secondary or estimate. If a better direct source appears, the row should be updated.

7. Update policy

Source pages do not update on the same schedule. Nintendo updates regularly. Sony mixes a current PS5 line with older legacy milestones. Estimate rows may stay unchanged even longer.

When a figure changes:

• confirm the new number on the official publisher page if available,
• check that the table label still matches the true source type,
• update related editorial notes if the interpretation changes,
• avoid changing dates or wording unless the underlying content changed.

8. Worked example: how the Switch row gets its number

Nintendo publishes lifetime hardware shipments per platform in its investor-relations data every quarter. The Switch row on this site takes that published lifetime figure as of the most recent fiscal data set, notes the as-of date, applies the Official label, and links the IR page from the Sources list. Nothing else is mixed in: no analyst forecasts averaged on top, no tracker numbers blended with the company figure.

When the next quarterly file moves the number, the row moves with it. If Nintendo one day stops reporting the platform, the last official figure stays in place with its date, and any newer market estimate would have to enter as a clearly relabeled estimate row instead of silently overwriting an official one.

9. Update cadence and revisions

Updates follow the platform holders' fiscal calendars rather than a fixed weekly schedule, because that is when real numbers actually appear. Nintendo and Sony quarters drive most official refreshes; estimate rows get revisited when a credible secondary source publishes a meaningful new reading, not every time a tracker ticks upward.

The site shows the current state of knowledge, not a version history. When a figure is revised, the table and the related profile copy are corrected together, and the source link always points at the document that supports the number being displayed today. Readers who need historical revisions can follow the same primary links the site uses.

10. Why this methodology matters for trust

The table should be easy to check. This page exists so readers can see what the site counts and how uncertain rows are handled.
