A good comparison for differences is take a look at the Rogue 3 pack-in figure, iFett... Compare him to say the VOTC X-Wing Luke... The Snowspeeder costume has the coat Spuffy mentioned, and it puts a big puffy collar up around the neck, a jacket extension below... Luke's got his sidearm too in a holster, and the gloves and boots are Hoth gloves/boots, not the black Yavin IV/Endor pilot boots/gloves as was mentioned...
And his harpoon accessory wouldn't be anything too disappointing to get too, haha.
I'd love all the Hoth Pilots to get new figures really... Wedge, Luke, Dak, Hobbie...
