Vita weekly sales up 6,000 in Japan despite no new games

The Vita sold over 21,000 units last week in Japan according to Media Create charts and data. I'd like to offer a solid reason, apart from a Japanese holiday, but there are no new entries of any sort in the chart, with Dragon's Crown approaching 100,000 sales still in the top 20.

Ragnarok Ace should help things along when it launches next week, thanks to a good score in the latest Famitsu and its existing success on the Vita, plus the number of tie-ins in this version.
