There's like 30 people total that split their time between LOTRO and D&D Online with a few main devs representing the team for one game. It's still getting expansions and new content though. A new Monster class is getting added for the first time in like a decade. Class reworks are slow going but have been progressing. Some great, like Loremaster getting a non-pet spec, some bad. The main issue with the game really is the lag, which they've never been able to get a handle on. There's just random rubber banding and skill delay that make playing certain classes near impossible or just not as fun as their concept might otherwise make them.

I think they got a bit of a player boost from the Amazon LotR MMO being scuttled, and now from the TurtleWoW Private Server going down and people looking for something different but still old school.
