Changes in the retail horizon

From a thread on www.retailwire.com:

There has been considerable study done by WSL Strategies that concludes that we are in a society responding at retail to "supersizing" or "specializing." I would agree that to be caught in the middle is very unpopular ground and potentially a recipe for disaster. My belief is that specialization will ultimately dominate the landscape. Sure the super-big-box retailers will hold a commanding market position, it is those retailers that carve out a specialty niche and blanket the area of expertise completely that will be in a position to operate at a higher operating margin.
