Yes PC is fully digital, but if sony takes away physical games, there really is not point of having a PlayStation. No used games since they'll be digital only, sony will have a complete monopoly on them so expect prices to rarely drop, and no $80 subscription to play online, which will probably increase in price soon. So yeah it doesn't make sense to have a digital only console when PC is much better.

PC may sell most of it's games digitally, but at least there is competition and decent sales! Sony's PS storefront is terrible! Prices are rarely reasonable, and even older games are still relatively pricey! You can compare games quite easily for yourself. Check out a reatively new (6months or so) game on both and i'd like to bet the pc version is considerably cheaper. Plus, you don't normally have to pay for online play!
