Dpreview posted an interview with Masaya Maeda Managing Director at Canon, and he said two interesting things about the EOS-M system
1) The Canon EOS-M didn’t sell as expected.
2) Nevertheless there will be new lenses for the EOS-M system within 2013.
It's not all bad though - one more prediction comes from MR-Maeda: There will be “an increase in the number of full-frame models”.
