ShopTo is listing the same Animal Crossing: New Leaf 3DS XL bundle that came to Japan when the game arrived there last year. The site's description says it includes a 4GB SD card, and prices the polka-dot bundle at £190, which is the same price the Monster Hunter 3 Ultimate and Fire Emblem: Awakening XL bundles are going for in the region.
Nintendo hasn't announced an Animal Crossing: New Leaf bundle for Europe (or North America), and ShopTo's listing has the same Japanese-emblazoned box as above, rather than a new English one. Having said that, its emergence just ahead of a Nintendo Direct broadcast is a bit suspect. Maybe we'll frond out tomorrow if the bundle is coming to town along with New Leaf in June.
Update: While it still appears in a Google search, ShopTo has since removed the listing.
