So, looking into what is happening at Sledgehammer:
Before the layoffs and restructure they had 3 studios, the main one in California, a 2nd one in Melbourne Australia opened in 2019, and a 3rd in Toronto Canada opened in 2021 (by August 2021 they had 450 devs, 290 in California, 150 in Melbourne, and 10 in Toronto, before these layoffs those numbers had increased to 580 devs with Toronto having grown to about 100 devs and California and Melbourne studios also having grown some over those 3 years). Also in 2021 Sledgehammer's COO had announced that Sledgehammer was becoming a multi-project studio, and it was believed that Sledgehammer had a 2nd team working on a new IP. Then yesterday when the CoD roadmap leaked at Insider Gaming, it was stated that Activision was closing the main studio in California and that employees in California would be work from home until at least the end of 2024 when a new, smaller headquarters could be found/built. Now today we find out that 30% of Sledgehammer has been laid off, which would explain why the larger headquarters in California was no longer needed.
The question now is, were the 30% laid off from the CoD team, or were they from the 2nd team, the one established in 2021 and believed to be working on a new IP? Maybe a mix of both, with the larger amount removed from the new IP team alongside a cancellation of said IP? Only time will tell.
