There is deffo a quad core model, which is why I am confused with people indicating there will be a super cheap 6 core chip..
Quads will probably be Athlons, that's why. It'll be a pretty shoddy chiplet if only half of the cores work, and a bit of a waste to put that into a Ryzen. Plus with 3 established Ryzen tiers, if AMD stick with 4, 6 and 8 cores for those tiers as before, does that mean the new 9 tier is for 12 cores? What about 16 core CPUs then?
I think we'll only see quad core Ryzen 3s if Ryzen 9 doesn't have 16 cores. And since Su and Papermaster have spoken about improving their single core performance to match their established core count leadership, I think they'll likely press home the latter by shifting the Ryzen base line to 6 cores, leaving the half-working junk chips to Athlons.
