Not a "furry expansion" as I first read. The PS blog has the details with a some 24 new levels from the WipEout HD Fury game ported to the Vita. If you already have them for the PS3, then you can download them for free.
Vita owners can pick up all 24 tracks, zones and ships for £9.99 or there are two smaller bundles available. That's kind of a shame as the awesome PSP WipEout games had loads of free DLC, but I guess times they are a changing.
