Was pretty excited to see a Warhammer Online beta in the works:

Looks like the current beta is locked at lvl 12, which is tier 1. Had tons of fun playing this game when it first released, had some pretty unique RvR pvp that was compared to DAoC. On live I pretty much leveled up and geared up completely on pvp, a feature I'm still surprised to say hasn't been implemented in very many games.
I'm sure the launch is far off, but from the looks of it, alpha could still be a lot of fun.
