Sonic Generations was originally slated for Wii and DS
Sonic Generations was one of the few recent entries in SEGA’s long-running series that never made it to Wii. However, it seems there were initially plans to bring the game to both Nintendo’s console as well as the DS.
In a new report, Unseen 64 writes:
The next update on Sonic Anniversary came from Madrid’s Gamefest 2010, courtesy of Sonic news site, Sonic Paradise. As corroborated by Sonic Reikai, a SEGA representative reportedly let slip an abundance of information on the game to one of their reporters. Without the authorisation of SEGA, the rep. disclosed that it was to be a combination of 2D and 3D gameplay, and would be developed for Nintendo Wii, PSP, PS3 and DS. When asked whether or not it was planned to come to Xbox 360, the employee indicated that talks were still ongoing.
Eventually, the game was officially announced as Sonic Generations on April 18, 2011 for Xbox 360 and PS3. It is uncertain how far the Wii, PSP and DS versions progressed, but our sources suggest that they were cancelled not long into development.
