Last month, on October 21, they filed trademarks for FIREBALL and FIRE BALL with the United States Patent and Trademark Office. For when the links expire, they can be seen at serial numbers 97086693 and 97086680.
Looks like they're going to cram it into their northwest corner, close to the swings. The miniature disk'o ride and teacups in the immediate vicinity have already either been dismantled or repositioned elsewhere (both are staying). It will be located a ways away from the two existing coasters.
I guess there’s not that much they could do with a plot that small - good on them for installing a coaster that kids may enjoy (and view as a bit intimidating given its height), even if the experience for adults is reportedly completely meh.
Wow; that site is tiny! I don't know if the picture is throwing the perspective off a little, but that plot doesn't even look big enough to hold something like a kiddie coaster (certainly nothing larger than, say, a Zierer Force Zero or Zamperla Family Gravity Coaster 80STD), so to fit an RES Roller Ball in there is an incredible use of space by the park, in my opinion!
I'll plug it in here since it is relevant for anyone interested. I talked with Jeanine who is part of the family that owns Adventureland about many different aspects of the park along with Fireball of course:
