Sega of America recently filed a new patent with The United States Patent and Trademark Office for a ‘Sonic Rush Adventure’ title, this has lead to speculation that a Sonic Rush sequel is on the way. It is worth bearing in mind that companies register patents and trademarks all the time, and only a selection of them ever come to fruition, but given the success of the previous Sonic Rush title, it seems fair to assume that this particular game will eventually come about. Although we don’t know any more about the games of yet, the name alone brings back memories of the ‘Sonic Adventure’ Dreamcast titles, leading some to believe that the new game will feature at least some elements from those two titles. We will just have to wait and see whether this comes in the form of 3D gameplay, some sort of central hub/exploration areas, or something entirely different. We’ll keep you posted with the latest updates. From here. So yeah could be something, could be nothing. But if it is a future DS title PLEASE FOR THE LOVE OF GOD DON'T BE IN 3D!!
