Mostly physical. I'd buy more digital if the memory cards were cheap though. Plenty of sales on PSN, but no space and I don't want to delete my data and prefer to reserve my cloud storage for PS3 games. And ... I generally prefer my main collection to be physical. I'd only buy the games I am less than interested in on PSN. Indie games like Guacamelee and Velocity are purchased on PSN, of course.
Playstation = The Beast from the East
Sony + Nintendo = WIN! PS3 + PSV + PS4 + Wii U + 3DS
