Yup - though it'll default to Japanese, which I think is a good choice for the "definitive" release.
And thinking it over... wow, this really is a GREAT deal, isn't it? 42 episodes for $80, along with, I believe, a free booklet and some fancy special features. Now, I'd bet Amazon and other such retailers will be chopping the price down to $70 or even $60! Factor in the booklet, worth a good chunk of change in and of itself... that factors out to roughly a dollar an episode. Consider most boxes can be up to THREE TIMES that, well, it's a bargain if I've ever seen one.
However, I'm still going to wait on it. They've confirmed the movies are getting a Dragonbox, too, so I'm betting Dragonball and GT will be getting one, too, eventually, and I'm waiting until I can start from the REAL beginning.
And now I'm nervous about buying the new Dragonball sets, if they do release a Dragonbox version at some point.
