Because of New Year's festivities, Sony has updated the PlayStation Network a day earlier than usual. This week brings a bunch of discounts for some of 2012's best, including a few bucks off Sound Shapes, Skullgirls, Tokyo Jungle, Shadow of the Colossus and many more. Of course, if you're a PlayStation Plus member everything is discounted a tad bit extra.

PS Plus subscribers also get their requisite free games this week, including NBA Jam: On Fire Edition and PS Vita puzzle-platformer, Chronovolt. Both of those are available in PS Plus members' Instant Game Collection right now - for the full list of this week's deals, hit up the PlayStation Blog.
