The 7D has dropped in price since its introduction, but there is little competition from Nikon's older D300s to really force a big drop. Once a D400 comes out, the price will drop and a MK II introduced.
You can do what I did a year ago, I had a old damaged Canon 35mm SLR that I traded in for a refurb 7D using the Canon CLP and got about 15% additional off the refurb price. Its a very nice camera, and works great.
