Sega have teased on their Sega Blog that a new Sonic Jump game is coming. the game is coming to mobiles which should mean android and iPhone, with an outside chance of Windows Phones. a quick look on the internet reveals the original Sonic Jump game as a game where Sonic would jump and you control the platforms he lands on. my guess would be the new game would give the player more control over jumping.
