Valve's most recent CS2 map pool adjustment came in January 2026 when Train was removed and Anubis returned ahead of Premier Season 4, followed by the late-April addition of a reworked Cache to competitive modes. No official announcements or patch notes since then have signaled further rotations before the June 30 resolution date, and changes historically align with new Premier seasons or majors rather than mid-cycle tweaks. With the Cologne 2026 major on the horizon and stable pick-rate data across the current active duty maps, traders assign minimal implied probability to any listed removals. Late scratches or sudden Valve updates remain possible but lack supporting evidence from official channels or recent form.
