I know there's a market for it for cars... which I am interested in from a spectator standpoint, but if I am ever to actual enjoy using it myself, there'd need to be enough interest to have the odd motorcycle track day (and I don't mean drag racing... I hate that garbage, as well as ovals).
Can't imagine them skipping on an oval, considering the redneck demographic in the 'parasite' communities.
Hopefully the graphic they chose for their website is indicative of their primary interest in a world class road circuit:
