The "Day 1 Digital" thing may have ended, but you can still frequently buy games digitally on day 1 on PSN. Case in point: Crysis 3.
Perhaps the exact opposite of Crysis 3, at least in terms of processor requirement, is Capcom Arcade Cabinet. It's out now, a free download with a free copy of 1987's Black Tiger included, and more old arcade games to buy. On Vita, Patapon 3 is now available to download, and be sure to get the free Maverick Hunter X if you're a Plus user. Check out the full release list at the PlayStation Blog.
