Man every game on that list has me hyped! To think a great many of them are do fairly early in the year. Portal 2 in April? WOOT!
As to GW:2 it certainly does seem to be doing some stuff that redefines the genre. Stuff that seems like common sense changes that will make for an amazing game. While a lot of the other MMOGs in the works seem to be just WoW clones with a few gimmicks to switch things up.
Speaking of MMOGs, I just picked up DC Universe Online a few days ago and I haven't played anything else since. If any of you are super hero MMOG fans (CoH, ChO) this game is a must try. It has fantastically fun combat, great story-lines where you interact with classic DC heroes and villains. I was up until about 4am last night (extremely late for me) doing a story-arc that concluded in taking on Scarecrow with the help of Wonderwomen (the 'mentor' of the character I was on). It was a crazy fun fight. But yea I cannot recommend it more to comic fans or superhero MMOG fans.
