Risky could mean a lot of things:

1. Risky without Tanaka in general, she was the face of it. Removing her already seems risky.

2. Going for a different kind of song. Maybe something more energetic that doesn't sell as well or something

3. A cover song. They normally don't sell too well.

4. Giving more lines to one of the less popular people. If they gave more lines to Zukki, Eripon or Harunan that would be risky. All the 2ch Riho loving people would freak out and maybe not buy it because of that.

5. Maybe they won't release it until 12th generation debuted (probably won't happen) and so having new girls in it. And without a current clear lead. Could be risky.

Who knows...Tsunku needs to announce it already.
