Sonic Generations

I think the 3DS games are from all 2D Sonic Games, not just the handheld.
 
They said that the 3DS version was gonna focus more on the handheld titles of the series.

They didn't say that the 3DS version was only going to have levels from the handheld titles.
 
To many plain and city stages are being put in the 360 or PS3 version.
