Most the scenes in that trailer are from Uncharted 3, which concerns me that the "re-mastering" didn't do much to enhance Uncharted 1 graphically (i.e., put it on par with U2 and U3, though it already looked pretty amazing for its time). Though perhaps the reason for the U3 focus in the trailer was the decidedly different appearance of Elena in that game compared to U1 and U2.
None of the new modes particularly interest me, especially Brutal Mode, as I would be hard pressed to complete any of the games on even Survivor again at this point. And if I remember correctly, U2 and U3 already had an easier than Easy mode if I'm looking to play through again just for the story and visuals.
I still haven't played Uncharted 2 or 3 so I'll be getting this for sure. I'm not sure I want to play Uncharted 1 again though. I liked the game but by the time the supernatural enemies showed up near the end I was more than ready for it to be over.
Everything I have read says that 2 and 3 are much better experiences. I'm not saying Uncharted isn't a good game. I'm just not sure I need to play it again.
