Spotted a couple of ponies in the holiday aisles at Target today. There's a G4 Sweetie Belle with a scarf with snowglobe-like packaging, and a re-release of A Very Minty Christmas DVD with a Minty Ponyville toy (same as the advent calendar last year I think). Photos
here.
(Sorry if this is a repeat, but I didn't find anything in a search. I'm totally obsessed with holiday ponies, so I've been on the lookout).
