Manifest V2/V3 timeline update?

Google/Chromium announced at the end of March that MV2 would be completely removed from Chrome in v139, meaning that v138 will be the last version that can run MV2 extensions even using the policy override. Since v139 is expected sometime in July, that time is coming up fast!

In Microsoft's timeline, it is stated: 

Manifest V2 extensions will continue to be supported through Enterprise policies at least until the date in the Chromium Manifest V2 support timeline.

Since Google will be removing it as of v139, can we expect the same for Edge? Just trying to plan out notification to some groups who use custom extensions (ie: from vendors or internally created) that they will see the older extensions be removed/disabled. 

Thank you!
