Well, there is the Digimon Savers/Data Squad Movie, which never got a dub because it never released over here. And the X-Evolution movie, which also never got a dub. As long as they're willing to let those two be subtitled-only, they'd still be able to have 3 movies on a third collection. Maybe they could add in a few of the shorts or something to pad out the run-time a little, since the Savers "movie" is only a 20 minutes long. I'll admit, it might be the least appealing collection, and I'm not sure it'd sell as well as the Adventures-era stuff. But, it's doable.
