The 2400G, which I think is currently the top desktop APU, launched in Feb. 2018 and has four cores.
Though that temps are higher because of that, resulting in more work for the cooler, is not ideal for a CPU that's apart from that great for a HTPC.
Regardless, I do expect G parts will be announced soon, too. 3 CPUs definitely isn't a full lineup.
For the vast majority of professional use cases 8 core / 16 thread running at 4.5+ boost is going to be way enough for a while. AMD sure has spoiled the market in just two years on commoditizing 8 core desktop chips because in 2016 the conversation would be about what flavor of $400+ quadcore or $800+ sextacore from Intel you were going to get.

Hardly the latest technology but you can plug a monitor into it.
Here we are, 8 years after Apple started shipping "Retina" displays, and PC software hasn't caught up. It's embarrassing.
