Just to be honest, Sonic Boom isn't really that good, but however, Sonic X was super popular. It had left off with many cliff hangers. There's been lots of fan art of a new season of Sonic Xand many number 1 fans have been wanting season 4 as well. If the Sega production company was to make season 4 of Sonic Xand end Sonic Boom for good, they would make much more cash and would make a lot of number 1 fans bright and cheerful.
