In a blog post entitled "With new security and intelligent features, the new Gmail means business", David Thacker (Google VP Product Management, G Suite) announced, "We’re also introducing a new way to manage work on the go with Tasks."
The new refreshed Tasks system will be available on the web and have accompanying mobile apps (Android and IOS). The new updated Tasks system will allow you to create tasks & subtasks with due dates and notifications.
The current tasks was an anemic stand-alone product that barely worked. The new one will integrate into the G Suite and allow you to drag & drop emails from GMAIL, files from Google Drive and more.
