A couple of weeks back the Japanese commercial of Sonic Generations aired and showed what looked like Windmill Isle from Sonic Unleashed in the 3DS version. Now it turns out that everyone on the internet was wrong about this, as according to the Spanish Official Nintendo Magazine it’s the other stage with a Mykonos-inspired background, Water Palace from Sonic Rush. This means that one of Sonic’s handheld adventures is being represented on the 3DS version after all. Besides this, the magazine gave it a 90 out of 100 in their review and mentioned that there are more than 100 missions.
