Big Finish will be doing a series of The First Doctor Adventures with David Bradley and his costars from An Adventure in Space and Time reprising the first Doctor and his original companion team. Source.
"This series of adventures pays homage to the beginning years of Doctor Who, and each of the four episodes in each story will be given an individual title. Two of the four stories are historical, focusing on tales from Earth’s history pre-1963. Back in its first few years, Doctor Who was intended to be an educational programme using time travel as a means to explore scientific ideas and famous moments in history, while still captivating the minds and imaginations of generations to come."
Plus, "the First Doctor will encounter his greatest foe, the first incarnation of fellow Time Lord, the Master, played by James Dreyfus."
I'm far more excited about Bradley reprising the first Doctor than an even earlier incarnation of the Master, tbh.
