As the DEVs said, Valheim will get 10 Bosses. Until now there are 5 Bosses. The next update will bring the sixth one. I guess Valheim leave early access when the tenth biome with boss is released, not earlier. The target was 4 updates per year. But the last ones took a lot more time than expected. 3-5 years sound realistic, like Shaft said.

Its been out 2 years or so already. 0 major patches. Your math is off.
