Physical edition is a no brainer for me. I hope society understands that eventually it will be far more expensive to own the digital edition considering all game prices are in possession of Sony and their PS Store. Whereas with physical you have not only access to price drops/sales of hundreds of retailers, but also used games.
Still, I am going to let this generation pass me by. For now. I looked at all the games from the current generation I still want to play and thought: nope, I'm fine where I am. So I will be waiting, at least until a slim version or such is out.
