I think the name reveal will work in much the same way as the "he finally finds out who I am" River Song reveal. The fact that she's Amy's daughter is a bit of a poor reveal, but coupled with the fact that Amy's daughter was Human+ and had been kidnapped/brainwashed to kill the Doctor it makes it a lot more meaty.
Similarly, it won't be a simple "I'm called Dave, get over it" - I'm guessing we'll hear something along the lines of a dark character in Gallifrey's past who even Timelords were afraid of, and his name will turn out to be the same as the Doctor's name...
