yeah thats the big issue here
sony gives the consumer an option of physical or dd
ms is forcing dd, even when you buy a physical disc
Not to mention with DD on the Vita or PS3, in many cases you did get preorder dlc for Day 1 digital games on PS3 (typically some theme or the same digital dlc retailers had).
For most Vita games, its been the same thing EBgames/GameSTOP has offered in digital cosmetics or boosters or digital soundtracks that come with buying the game digitally off the PSN store within the first week.
If I didn't get preorder deals, I would definitely go digital only considering I don't pay 13% HST where I live like I do with retail making it more cheaper than retail discs, but also enabling me to get the same preorder dlc available with retail.
I could care less about steelbooks and physical preorder doo-hikkies. The convenience of being able to play a game without swapping discs straight from your harddrive is the best experience.
