I agree with comment above, it's not a new concept that the larger tracks, although fun to watch as a fan at times, are hard on engines and often result in midgets getting torn up.

I read into it as Miller actually is hearing what people are saying and may restructure the schedule to stay on smaller tracks much like Powri. Now, what that would do in terms of events like the 4-Crown and what not I'm not sure and that's why I'm not jumping to any conclusions.
