Ticket discounts for 2016 Disney races?

The last time I was involved in a runDisney race, my family participated in the Princess Half-Marathon weekend in 2011. Back then, an event code was attached to the registration for discounted park tickets. When I signed up this year, there was no such code. I am seeing on the runDisney site that apparently the last event to receive codes is the Wine and Dine 2015. Is Disney discontinuing the ticket discounts for 2016 races?

I would guess so. Run Disney events are gaining in popularity and selling out earlier each year. Disney is losing reasons to add incentives.
