yeah. Also the doctor is a timelord, as is the master, who has already changed gender. So doing it is consistent with the world they've created.
It's apparent now that this was their plan starting a few years back to create an angle for this to happen as the whole gender switch thing wasn't part of the background story until the last 3-4 years.
The Master all of a sudden flipping genders was also unpopular back when that occurred.
