There has been conflicting stories on whether borderlands 2 will have an increase in levels or not. According to both Forbes and PC Gamer (both credible sources) say that the cap will increase in March. However I found a recent article from Co-Optimus that suggests otherwise, stating something on the lines that the 'math involved to increase the cap would wreck the game.' Check it out, let me know your thoughts.
