Watched some video about GW2 (I never played GW1) and it does look really good. Don't think I can go back to WoW after seeing how good these new MMOs like Tera and GW2 look. They're stunning. I was going to pre-order GW2 today to play the open beta this weekend, but they're all sold out:

Only the collector's edition ($150) is left at this time. =/
So I ended up ordering Tera. GA isn't until May 1 (Tues), but head start begins tomorrow morning if you pre-order. Your character from open beta last weekend carries over too, so that's cool.
