Somehow I doubt its that simple. Many people relate things too much by price, when really the majority of mainstream sales is brand appeal. Why do you think Rock Band, Guitar Hero, Wii Fit, ect can all sell so well despite having pricetags double and triple than that of other titles. Brandname.
It's not as simple as just what the pricepoint is. It's a factor in sales, but not the only one, and surely not the most important one.
