Yeah, in the Doctor Who 50th Anniversary Special, the War Doctor did say that he won't remember "any of this" as he farewelled the 10th and the 11th.

I watched the new ep with my daughter next to me. I've told her nothing about the new Doctor because I wanted her to watch it with a totally fresh and uninfluenced opinion. When she saw the regeneration she started immediately smiling from ear to ear and was then jumping up and down with excitement and also ran over to the TV to get a closer look.
