My local FYE had had that (and some Spiderman 3 Sandman statues) in stock for months and months. Actually, they have about 50-60 copies of Dark Knight in various forms.
I'm in the same boat, but are these really that rare or did people just buy them like crazy? I was looking on Wal-Mart.com and noticed they have the limited edition Dark Knight Blu -Ray that came with the bat-pod for $25. Huge Batman fan but and would love to have this, just not sure if it will be super rare or not.
Thinking about picking up a Steelbook solely to sell on eBay. Already own Begins so I am good.
