Well for a start there's all the optimization of the game. I was talking more in terms of a lot of work still left to be done to make it final-release worthy. During Beta most people were reporting it only using 30% of their CPU power and hardly any of their GPU. Plus we were only allowed access to 3 out of the 5 races, and even then only the first 1/3rd of those races' level content (probably a lot less if the XP/level scales exponentially). We had just a glimpse of the game, and even then people made a lot of constructive feedback and suggestions!
I just want the game now, lol. It would have been nice to have a persistant open beta, but I doubt they'll do that though as they're probably counting on a percentage of people not having easy access to the beta to "demo" the game, and thus to prevent lost revenue from speculative buyers who end up not liking the game.
