Answer:
mid-calorie soft drinks such as Pepsi Next (2012) have not been successful in the past.
Explanation:
The new Pespsi true is a great product that offers the advantage of having the same flavor as Pepsi but lower calorie content of only 60 calories. This should sell well with consumers that are looking for lower calorie options.
However if there was a similar product like Pepsi True called Pepsi Next in 2012 that was mid-calories and was not successful, this could be a show stopper. People's perceptions of Pepsi Next will affect Pepsi True as they will feel it is just a repackaged Pepsi Next.
This will most likely lead to failure of the product similar to what happened with Pepsi Next.
