On the verge of + gerund is used to describe an action that is at the very point of happening (the immediate future). The clue "any minute now" confirms this immediacy.
Given the sheer amount of global media hype, the launch broadcast is bound to break all previous viewership records.

The future perfect (will have done) is required here because the time marker "By the end of this decade" sets a future deadline before which the action will be completed.
