Happens every console generation. The only time this doesn't happen is consoles that "failed". The Wii and DS still got major titles 1-2 years even when the Wii U and 3DS were out. Since the Wii U failed Nintendo and 3rd parties didn't support it after the Switch came out whereas, the 3DS succeeded and still got major titles in 2017 and 2018 from Nintendo and 3rd parties.
It all really depends on how successful the previous consoles were. Microsoft, Sony and 3rd parties just cannot ignore the Xbox One or PS4 yet with how successful they were and how much software sales they still get from them.
