There's two possibilities. Atari is doing the bare minimum to keep the license. Or nobody wants to develop games off it.
Given the niche nature of RPGs at the moment (we have what, three developers focusing on it?), I'm leaning towards the latter. Bioware supposedly doesn't want to do them anymore. Bethesda has its own publisher, so they can't use Atari's license. And there's Obsidian, who knows if they're interested. So Atari is left with less prominent developers and smaller projects.
Then again, that's kind of what Atari's business model is at the moment anyway. They'll occasionally drag something across the seas, but all they're funding is downloadables. So third possibility. Atari isn't interested in doing what's necessary to make something we would consider ideal.
