Kathleen Kennedy is a highly respectable producer, Michael Arndt is a great writer, and J.J. Abrams is a fantastic director (and with him comes more than competent film editors and costume designer). Also, John Williams. Also Lawrence Kasdan.
In terms of the content, all we know so far is that they are going to try to bring back some practical effects, and the that Mark, Carrie, and Harrison are all but confirmed.
Besides that, I think the best aspect of the ST at the moment is that we don't have any information. The potential for these films are boundless. They won't be based on EU stories so we truly don't know what will happen or how it will all end, unlike those prequels that we all love so much.
So yeah, the ST is shaping up to be pretty awesome.
There are so many Sequels that fail with great talent around. Look at the Jurassic Park: The Lost World or Indy Jones Crystal Skull, both directed by Spielberg, and both are awful movies.
The big thing is where they are going to take this story and will it be original, yet still gel with the other SW films? That's a tough thing to do as most movie franchises start to get boring by the 3rd film, because there is only so much you can do before you start retreading older plot points.
Right now, I am reserving judgement on the ST, because nobody really knows anything about the story. But I have seen too many movies that are surrounded by great talent fail because the script/story was bad or not interesting.
