To summarize:
- It had a price drop and was already priced fairly competatively in Europe (i.e. amazon.de bundles; Argos UK bundles).
- All of Sony's systems are the face of the Champion's League, so get plenty of advertising through that.
- Nintendo's numbers for the year had Vita doing better than we've been tracking it all along; so these numbers reflect what will be a continuing upwards trend towards the holidays.
