2017 Game Design Animation Challenge MS/HS Only?

I noticed that the 2017 VRC Game Design Animation Challenge is listed as being open to only middle school and high school VRC participants. This seems weird since all of the other challenges that are open to VRC teams are also at least open to VEXU and many are open to IQ as well. What is more, last year’s game design challenge was open to all programs.

I was wondering if this was merely a mistake, or what the logic was behind closing the competition off to MS and HS VRC teams only and if the other programs will get a similar challenge of their own?

This challenge is open to VRC middle school and high school only in order to give the participants a chance to compete across a more level playing field, as this challenge does not award separate prizes to age/grade categories.
