Originally discovered by the Sonic Stadium and reported on by ‘Sonic News Channel’, Sonic Boom might be facing an end in the near future. The rumor states that the sub-series of Sonic isn’t meeting SEGA of Japan’s expectations and after the second season is fully complete, the series will be shut down.
This is a rumor, so this could easily be false. Please do not take this as an official announcement from the different branches of SEGA or Sonic Team.
I am hopeful this rumor is false, as I personally enjoyed the cartoon and thought the latest 3DS game was a greatly improved game.
