I've thought about this for a while and to come to a conclusion- Firehawk being removed might actually benefit the park in a lot of ways.
Firehawk was a hand-me-down coaster from Geagua Lake so it never felt like a KI coaster to me as the others do. Its placed behind Racer and Flight of Fear so it always felt "hidden" to me, and not a good "hidden" like The Bat.
The ride, while visually pleasing, is in fact very outdated in numerous ways. For one, the chain is obnoxiously loud, especially when its inches away from your ears. Second, riders have to keep their eyes closed during the slow ascent up the hill since they're staring into the sun. Third, the capacity is horrific to the point where a dual loading station seems to slow the loading process down. Fourth, the ride is incredibly short for how long you have to wait in line. Even though B&M Flyers might have the same capacity issues, they are worth the wait because you actually get a lengthy ride on most of them and experience awesome elements. Firehawk always seemed like a circumstantial ride to me- if it was cloudy or overcast or the line was insanely short, I'd ride it- and I'm sure I'm not the only person who's done this. The park hasn't even made any attempt to repaint the coaster as its showing its old green livery from when it was X-Flight; painting a coaster doesn't always suggest that its going to stay, but not painting it at all says something.
I feel like the ride is really starting to show its age. I can only imagine how much of a maintenance nightmare it is to keep running. Getting rid of it would ease some of the stress put on maintenance, funding, and resources which can be put into other rides that may need it. If the park replaced Firehawk with a B&M giga, they wouldn't be as many maintenance issues as they currently see with Firehawk and would be a good ROI in my opinion. I always thought that a giga would coexist in X-Base with Firehawk and Flight of Fear, but now I'm starting to think that it might not be the case. In addition, the last time KI removed an unreliable coaster, they replaced it with something that made up for it. If we have to sacrifice Firehawk to the coaster gods in order to get a giga, I'd be for it.
In addition, I honestly don't think Vortex or WindSeeker will bite the dust just because the park wouldn't really gain anything from doing so, especially when Firehawk frees up a lot of land for expansion. However, if WindSeeker does bite the dust, I wouldn't be surprised that they wouldn't announce it earlier so people could get their last rides since you could go to WoF, KD, CW, CWS, or CP to get your fix.
Addition. Also, Kentucky Kingdom announced their next attraction will be called "Kentucky Flyer." What's interesting about this is that if Firehawk is getting removed and going to another park, KI fans can always go to KK to ride it if they're feeling nostalgic. I think its a weird coincidence that there's rumors of us loosing something that flies and Kentucky Kingdom gaining something that flies.
Just my two cents. I could be 100% wrong.
