Even if there was a direct support for CDR in Carrara, you would probably still have to save in an older CDR format. In essence you would be required to take the same steps now that you need to take for exporting an .ai out of Corel. The reason I say this is because I don't think Eovia would support Corel 12 right out of the bat. They don't even support the last three versions of Illustrator for that matter.
