Symbian Carla and Donna updates under construction; Belle probably delayed to 2012

Looks like Mr. Blurrycam visited Nokia Developer Day at Mexico and managed to snap this

Yeah its in spanish but you can read the details in english below

So Carla will be the last update for N8 and other Symbian^3 devices. Donna will be exclusive to Symbian dual core devices (probably the next symbian flagship)

Also the “Symbian Belle” column says Belle for X7, E6 and 500 in 2011 while for N8, C6-01 and C7 by Q1 2012. There are rumors of Belle for N8 by November end. Maybe the info above corresponds to country specific and carrier locked versions.
