Um, guys, the visual evidence is as conclusive as it gets without insulting the viewers' collective intelligence. He visually appears to have exactly the same fate as the other Time Lords. It's usually a good idea to apply rather than creating rather baseless doubt.

Euros Lyn depicted the event in a way that we have to respect. There is absolutely no visual distinction between the fate of Rassilon and that of the Master. They both fade to white, in the same frame, after Tennant says, "Back into the Time War, Rassilon. Back into hell!" The obvious read of the scene is that the Master goes back into the Time War, too.

There is zero visual or scripted ambiguity about what happens.
