Hi @ICCSDInnovation -
I spoke with a member of the Product Team, and they said that Instructure hasn't set a date quite yet. They also shared that we won't establish any type of timeline until Google has finished parity work with Google Assignments. After they finish and see positive experiences we’ll look at defining (and communicating!) a timeline.
To keep up-to-date on all of those timelines, please follow Upcoming Canvas Changes
