I don't know how successful Toqger was, but my guess is that the reason Kyoryuger got such an extensive lineup was probably because Kyoryuger toy sales were considerably successful. Its toy success was enough for Saban to skip adapting Go-busters and move straight to Power Rangers Dino Charge.

As for Go-busters, it was done during a time when Sentai Figuarts were still a big thing. The Gokaiger figuarts the year before seemed to have sold well enough, so Bandai made a gamble that Go-busters would do well. I don't think it performed as well as they wanted.

This is all just conjecture, and my hypotheses.
