Thinking of buying a PS4

Hey guys,

I'm planning on buying a PS4 soon, probably during the black friday deals. I've looked over the sticky thread about "PS4 Bundles & Firmware List", but I didn't find much info on newer bundles. So my main question is, does anyone know which 2018 PS4 bundles or standalones have the correct firmware to be exploitable? Also, is it possible to downgrade the firmware? And can you go online at all with a hacked PS4?

Thanks
