Physically, yes it is. It has Hoth deco though instead of the dirt on the overpriced Walmart release from last year. The new one also has some minor tweaks to the neck assembly to make it more stable. Of course it would have been nice to have a more screen accurate Hoth version with the different head at least, but it's a toy and Hasbro wouldn't spend the money on something like that. The vintage one, while grossly inaccurate, does look more like the Hoth one in the film, obviously because the toy was based on the first appearance of the "Scout Walker" in TESB.
My first batch of Rocket-Firing Boba Fett figures arrived today. The first attempt was stolen somewhere in the postal system, and Hasbro promptly sent replacements. Here's some comparison shots:
