The Beginning of the End of the Blocked Schedule?

Earlier this week (and just below this post), it was outlined why the blocked scheduling of tracks - both ovals and road/street circuits - needs to come to an end.

Now, it appears the first blocks in the wall are coming down.  Per USA Today auto racing writer Nate Ryan's twitter account:

New Hampshire Motor Speedway moves its previously announced IndyCar date from July 31 to Aug. 14 to accommodate mid-July #nascar race.

As the schedule stands right now, that race falls directly after Mid-Ohio and before Sonoma.  With rumors persisting that the Baltimore race will be over Labor Day weekend, it would seem that the blocked schedule is being adjusted rather sharply, though we should know more around Aug. 30 (though my money is on Labor Day weekend at Kentucky for a formal announcement).
