I'm very excited. Loved the first two games and then missed the third one.
I was getting pretty concerned about Conviction when they showed those first trailers, but since they've taken it in the new direction shown at E3, I'm very pumped again. I even went and bought Double Agent to pass the time.
Turns out it's really good too, though the menus are pretty clunky (glad that everything will transition smoothly in Conviction).
I never played splinter cell, even though I have the first one which game with my sound card. I saw the trailer and I have to admit it does look good, but I am not much of a fan of 3rd person fps.
Personally, I am waiting for StarCraft 2, I think the world is waiting for this game.
