Oh well. The ten dollar tickets were nothing to get excited about anyway. Based on the other artists, the $10 tickets were all in the concourse areas, tables outside the main venue with obstructed views.
Edit: The 7/24 $10 ticket information's been removed from the link you posted, mkb. Now it just says tickets will be on-sale 7/27.
Live Nation still says there'll be a pre-sale on 7/26 though.
