WI No Prussia, Prussian Hohenzollerns die out early (in 1568)?

WI Albrecht Hohenzollern and his brothers die childless and Duchy of Prussia is incorporated into Poland as per treaty of Cracow? What effect it would have on Brandenburg, Poland and the general history of the region?
 
Basically, your POD is no Duchy of Prussia, so no independant Prussia and one Partition power less...

That is just top of iceberg. When Prussian Hohenzollerns died out their Brandenburg cousins inherited not only their claim to Prussia, but also to Kleve and Mark

That's more than 200 years ahead of us, until then things can change in many ways.

Immediately Poland gains half million or so subjects, a couple of cities, and a good, nice waterfront which might make PLC more interested in naval affairs, and should help break of at least limit Gdańsk's hold on Poland's foreign trade
