Keep an eye out for golf ball display cases at department stores. They sometimes pop up as gifts for guys during the holidays and go on clearance afterwards. I was able to pick up several for $7-15 at Target one year. The ones I have each fit 40 Minimates, all behind a glass door.
I'm more concerned about durability than anything. Based on previous McF toys I've owned, I expect the blocks to just crumble when you attempt to put them together.
In context of the whole statement it does sound like he is saying the figures are a couple inches tall. Looks like it could be a cool displays for WD Minimates.
