I currently have 131 unbuilt models, including two chaos Rhinos, a chaos Land Raider. Almost all of them are either Tyranids or CSM. With the addition of several new Tyranid boxes (Trygon/Malwoc, plastic Gargoyles, etc), I should have roughly 200 models to paint.
I'm going to set up a schedule...I do well with check boxes.
It's going to be a good year.
