Regardless of the announcement (which are great additions despite being overhyped) KD is still in Cedar Fair's top 5. A giga, launched invert, floorless, a launch in the dark, an airtime filled dueling, and a incredible night woodie are things that no other park besides Cedar Point and Kings Island have.
I think a coaster is coming soon regardless of ROI, but Saturday's announcement is still nothing to get peeved over. However, with that being said, KD should still take note of the backlash on social media. It's pretty ugly.
