As far as I'm aware, Sony aren't actually doing the indie push as big as Nintendo; I'd have to check my sources on this, but last I remember was reading that Nintendo have more indie games in development than Sony and MS combined.
I've read that Nintendo were more forthcoming with distribution of the Unity engine, too, though I think Sony and MS are catching up on that. I'm sure there were a couple of other engines that Nintendo distribute for free, too.
