I usually buy hard copies unless I don't have a choice (and I've pretty much stopped buying download only games since PS+ started)
PS4 not being backwards compatible wouldn't stop me if I was though. I'm not quite sure how valid the "I was going to trade in my PS3 towards my PS4" argument actually is. If the PS4 included the required architecture to run PS3 games, it would probably be a lot more expensive and would probably cancel out any gain you would get by trading in your PS3.
