The biggest news for me is of course The Force Unleashed II. I was going to be excited no matter what, but nontheless it was a surprise and was a nice trailer afterall. Also one must admit Samuel L. Jackson is great at whatever he does. He announced the game in a very cool way... There is not much to tell at this point other than Lucasarts will develop the game internally.
Another exciting news for me was the in game demo trailer for Halo Reach! It sure looks handsomely awesome. There was a quote in it like "Spartans never die, they are just missing in action". That was a nice quote, motivating to do flagging @ XBL some more...
Conclusion is 2010 will be a great year for gamers. Batman Arkham Asylum 2, New Medal of Honor, tOR MMO, tFU, Halo Reach etc. etc. all comes in 2010. It'll be an interesting year for sure.
Anyways thanks to http://www.gametrailers.com/ for a great night and show.
