I dont think trenzalore will be the finale because how can the doctor knows the time when he will tell his name.

And the doctor is David Tennant before anybody asks

ok, thanks for the confirmation.

no, it is just a theory though.. what do you guys think it cant be trenzalore as that was introduced with the 11th

Theres a few interview quotes and magazine covers that have stated that Trenzalore will be in the finale. And in the clip with River where Doc 10 says "theres only one time I could", he may not know about Trenzalore, seeing as this is information the Doctor wasn't meant to find out.

Yes but he was talking about purposely telling someone his name, not being forced to.

The River in the finale could easily be a future one who he's told his name to but we don't know why yet.

Oh no he isn't....
