That is indeed GREAT news. It's very nice to see that Hasbro is actually putting out the Tauntaun that we expected they should
make when they originally announced that the new Hoth Han would have the lightsaber slashing action feature. Would've stuck out like a sore thumb to not have the split belly Tauntaun for Han to have his way with, when he's finally got the ability to get medevil on it's @$$ with a lightsaber!
Also worth mentioning is that Luke is very bowlegged, and indeed posed (only) to ride his Tauntaun here. Don't try putting him elsewhere in any Hoth dioramas, unless you've got a custom Rebel toilet nearby for him!
I'm just glad to see Hasbro putting the thought into making the various pieces/sets/figures all tie together in a cohesive manner like this (Han + Tauntaun). That's very encouraging that they're seeing a "bigger picture" now...
