If I were to guess wildly, based on absolutely nothing but a hunch, I'd suspect Mack would try to break into the "thrill coaster on a tiny footprint" market, where a lot of interesting designs have been made in the past few years. Stuff like Intamin's Impulse coasters (and later, Halfpipes and ZacSpins), S&S's Free Spin, Premier SkyRocket II, Maurer's Sky Loops, and maybe you could stretch the definition to encompass RMC Raptors too. Basically coasters that snake or shuttle back and forth on a tiny piece of land, using relatively few support structures, yet still being firmly classed as thrill coasters. Inversions not mandatory, but encouraged to bring that white-knuckle factor to a coaster that's practically just a junior coaster squashed flat and raised on its side.
It's a lucrative market because these coasters let parks build thrill coasters pretty cheap (see: Six Flags), and so a lot of manufacturers offer something that fits the description. The closest thing Mack has, despite its awesomely wide portfolio, is the Pulsar clones, and they only sort of qualify because they require a rather expensive lake as a central feature. But Mack seems to branch out in every direction, and I think it's reasonable to expect them to try this one too.
