This article is too definitive about the beta. I listened to the audio file, and the guy is talking about both Guild Wars 2 and Blade and Soul at the same time. He's pretty clear that NCSoft "will not have a major release next year", and he does say something about a closed beta or "public event" in 2010, but that could refer to either game, or both. The article should reflect that he didn't outright say "Guild Wars 2 beta in 2010".
I largely agree with Chaos Striker. Though I would point out that I am exclusively a PvE player and quite casual (though I have been playing the game since it came out). I don't play PvP at all, and I still really enjoy the game, and its graphics still compete with even the newer games out there, which I think is pretty impressive for a 4 1/2 year old game.
IMO the real selling point for GW is the value. If you at all care about bang for your buck, you can't find a better deal ...
