The movie has been screened now. Even WIkipedia has in the plot that it's heavily implied that Bond dies and she takes up the mantle.
He is apparently in a building that's destroyed by a missile? It sounds offscreen, so maybe it's not permanent, but it looks like this is what they're going for.
It looks like it's going to be mostly testing (buying 500M tests for distribution by mail on request), and some military reinforcements to hospitals and testing sites in high case areas.
At least that's what the early reports are showing.
