Disney has confirmed the rumored direct points increase for Disney Vacation Club Membership Extras in an update to the terms and conditions regarding these benefits on their website.
As of Friday evening the website was updated with the following information:

As reported early Monday over on the DVC Forums at DISboards.com, Disney Vacation Club is increasing the minimum direct ownership requirement to qualify for Membership Extras to 100 points, effective Tuesday – September 17th, 2019.
This is the first direct points increase by DVC since February 2018 when the minimum became 75 points for Membership Extras and perks. Prior to that increase, members were only required to have 25 direct points to qualify for benefits.
According to conversations with DVC Guides this week, all current blue cardholders will be grandfathered into this increase similar to 2018.
Individuals looking to lock-in these perks at the lower 75 point level are encouraged to contact Disney Vacation Club this weekend.
