Law vs Blackbeard caught me off-guard. Never predicted this, and not sure where Oda is aiming with this.
Obviously Blackbeard will probably end up getting the poneglyph copy, but on the other hand, we also know Blackbeard looks for powerful devil fruits, with Law's being one of the most powerful, however if he does take his fruit, Law would die, and i think it is implied that Law still has a role to play, at the very least with the immortal surgery plot, so i don't think it's Law's moment to die
Furthermore, Law is a D as well, so we're witnessing another D vs D battle, with the 2 having already being involved in the Rocky Port incident, which i hope will finally be fully explained
