In terms of consoles, the 5th Generation is pretty much just Saturn and N64 in this situation with not much else worth mentioning. Saturn probably cracks over 20 million and N64 cracks over 55 million, surpassing the SNES/Super Famicom.
Third-parties are left in a very awkward situation. Saturn is tricky to develop for, and N64 is tricky because of its cartridges and to some extent its wonky controller.
As @Jumpin mentioned, third-party either shifts largely to PC or to Saturn or N64 with the vacuum left from PlayStation. I don't think third-party would be evenly distributed.
And looking ahead to the next generation, Dreamcast could still very well be Sega's final console, but it would survive into the mid-2000s. By the mid-2000s, the industry would largely just be Nintendo and PC unless Xbox still jumps in, or PlayStation arrives late.
