I think retailers (particularly ones like Walmart, Target, etc), are grappling with the changes in the electronics marketplace. Just like music sections have drastically shrunk over the last ten years, traditional games sections are likely to shrink as well due to the influx of tablet & mobile phone products. I think ultimately it will come down what's selling vs. what's not - we may be reaching a point where in the next couple of years a handheld like Vita or a console like Wii U (which are shifting pretty small numbers), may not get 6 to 9 months (much less 1-2 years) on the market to prove it's a viable product before stores phase them out. We may be reaching a point where Nintendo/Sony/Microsoft have to hit the ground running with each launch or risk having its product banished.
Bah!
