If season two would come on May 2nd then why is the tournament being held halfway into june... that doesn't make sense. I highly doubt may 2nd is start of season two. I'v heard rumors that new AI bots will be released, a handfull of champions will be released on the release date, new items, new monster buffs, tons of new skins, tons of sales, rewards to long-term players, i have heard a lot of it and the only thing you can safely say is that in season two, things are going to get more competitive (riot stated so) and there will be new maps and changes in a lot small things to help the game be more balanced for competitive issues.
