Have you got a specific army your into?
I am currently working on a Rohan force (I picked up the Two Towers starting set when it came out), might continue with Isengard afterwards. My GF has started on a Harad army, and is already showing interest in an Elvish army.
I have always liked Dwarves, but they weren't available in plastic for a good long time. I can definitely see myself working on those as well.
All in due time though, I've still got a massive backlog of mostly unpainted and primed miniatures.
