"We would like to share some important news with you, first trailer of Uncharted on PS4 has been released! Where do you think Nathan Drake's fate will take him this time?"
You ask, "why do i have to believe this?". That's why - Playstation Russia back in 2010 with their Twitter leaked Mass Effect 3 reveal 3 weeks before VGA's.
We knew that Drake is almost 100% in this game, but some sort of clarification is always a good thing.
I can't wait for this game though.
edit: This is still the best theory out there:
Since it hasn't been posted yet:
"Every Betrayed us all" is not an incomplete sentence, Every is a name, Henry Every, he was a very famous British pirate in the 17th/18th century. And the guy speaking is probably Robert Drury, his ship wrecked in Madagascar and he was trapped there for 15 years exactly what this teaser shows. These events also happened in the 17th/18th century, so he must be seeking revenge from Every.
Yea i was getting worried that they were going to try and reboot it with new characters, and to me it would just ruin the series to not have Nate and Sully.
I hope so. Uncharted without Drake/Sully/Elena trio is like Halo without Master Chief, or MGS without Snake. Just wouldn't be the same thing.
