¿"Infinite" content?

These days and been thinking about the life time that the game will have 10 years are what they have planned for the life of Halo, but we know that it is difficult to give content even in this first year the complaints of the fans about the content that is in the game especially the events and the rewards that the game grants to the player, My big question is that it would be the best thing for this great game maybe they have to resort to repeat events or maybe weekly rewards. What I wonder most is how the player would react to this, would it be a positive or negative reaction?
