I really only go to this site. Back in college, I was all over Gamespot, Kotaku, and IGN. But, I work and travel a lot, now. There is something nice about only going to one place that only seems to cover the news I actually care about.
Sales for it haven't been a flaming horrible mess. So, I think it will carve out its own niche. As for third-party support, I could care less. If the limp third-party ports we got at launch are indicative of what they are willing to put forth, who needs them?
I am sure I will. I don't buy everything new at launch. But, I hit many of the high-profile releases on day 1 and pick up lots of other stuff used later on for cheap. I am also of the opinion that there will be at least 1 new console this year. So, that alone will take up the better part of a grand.
