Sonic Paradise has reported that Sega of Spain has gone back on their comments on Sonic Anniversary and retracted their statements. Here is a loose translation.
On the last day of Gamefest 2010, some board members attended the event Sonic Reikai to realize that this time Sega’s booth was in charge of a woman, and that the statements to the press about the game had changed.
Also confirm that is indeed Urretabizkaia Izaskun female (probably a she), the official in charge of the said retracted earlier claims that “could not” say anything about the next Sonic Anniversary. What is striking however, was not even consulted directly by the specific title.
