All of the content is down. Go to the forums on riftgame.com.
I don't know about the other guy but WoW end game was done in a few weeks as well. The people who completed the content had determination to grind to 50 at head start, get gear from the expert dungeons, than start raiding. Not only that, but most of the guild members they had started with were premade and had members from all different kinds of guilds from WoW.
As for me, I am a level 42 mage in Rift and the game is extremely good.
