Apparently 3dfx had a contract with Sega for making the Dreamcast GPU, but IPO'd in 1997. As part of the IPO they disclosed the terms of the contract, and the next gen console at Sega was a closely guarded secret at the time to avoid cannibalizing Sega Saturn sales (which were abysmal). The contract with 3dfx was canceled leading to a lawsuit. Then Sega of America CEO disclosed they were abandoning the Saturn for the next gen console. The console did not release in Japan until November 1998 and in America until September 1999. The CEO of Sega of America Bernie Stolar was fired just days before the release, partially due to these shenanigans, and the Dreamcast as a whole was such a failure it nearly killed the company.
