When does the Doctor discover he's going to die on Trenzalore, anyway? He couldn't have know it during Series 6, but the eleventh seems to expect the tenth to recognize the name.
Given that earlier the Doctor and Tasha go on about the nature of Kovarian's act of trying to change history and instead becoming part of it, I'd say its entirely possible the Doctor could do the same. TARDIS console rooms are stored - and that one's already been in use for longer than many of the others, perhaps it's now the default setting. I can't see the BBC changing it too drastically either. Its a standing set. Which makes Dorium's timeline interesting. Unless he learns it from a time traveller.
OP here. I am pleasantly surprised that so many people here dont automatically think the Doctor's Past/Planet's Future no longer happens based on, from what I can tell the very little evidence. The below(and no doubt other) articles seem to say without a doubt that those events will not happen. Can someone with the knowledge of how to edit the page, do so. So the above is reflected and explain it in the notes so other contributors don't revert it. At very least, it is unknown and should say as such. The next episode may explain it. It may indeed be why the TARDIS is crashing.. http://tardis.wikia.com/wiki/Siege_of_Trenzalore http://tardis.wikia.com/wiki/Trenzalore http://tardis.wikia.com/wiki/The_Doctor's_TARDIS#Destructions
My view is the Doctor changed history. If he didn't, then the storyline wasn't resolved. And it's obvious to me the intent was to resolve it.
Don't forget the genesis Ark. Millions of imprisoned Daleks. They were trapped or herded in there by probably an equivalent force. Remember Journey's End?
But wouldn't the Doctor seeing his own grave make it a fixed point in time and if he doesn't die there then it's a big paradox mess right?
That's not what a fixed point is. A fixed point is something you can't change with all your might. What happened here was a paradox (foreknowledge from crossing his own timeline.) which is just a messy complicated clusterfuck it's sensible to avoid if you have a choice before it spins more out of control. It's actually the opposite of a fixed point in time.
For example knowing that Amy and Rory are dead. So wouldn't knowing he dies on Trenzalore be the same?
Yes, exactly. That's my understanding as well. So, even if he doesn't die there, he has to do something to create that scar in time so that The Name of the Doctor can still happen.
