Well i guess there are a couple of concerns.
1. Is the space so crowded that everyone is just taking a smaller slice of the pie?
2. Do you think the FDA might crack down on Acai given its huge popularity?
3. It's not a "hot product" anymore...
Given that we are close to Q1 - read "I want to lose 20 pounds" new years resolution - i gotta think some argument can be made for these campaigns...
