Microsoft Gaming best year was $16.22bn, Activision Blizzard's best year was $8.8bn, PlayStation's best year was $26.9bn.
Even if you added MS Gaming best year and ABK's best year, it would give a total of $25.02bn which is still below PlayStation's best year. Though MS Gaming even without ABK may have broken records this FY due to Starfield and ABK without MS Gaming may have broken their record with the combination of Diablo IV and MWIII but once you add them together there's double counting and Sony's continued growth.
It's going to be a tight race for a while yet, potentially flipping back and forth.
