Here is the response I just received from Canon - very similar to what Grendel received. I specifically ask if the EOS-M or the M system was being discontinued. I added the underline:
"Thank you for contacting Canon product support regarding whether Canon will release the EF-M 11-22mm f/4-5.6 IS STM lens in the U.S. market.
Canon recently announced that the EF-M 11-22mm f/4-5.6 IS STM lens will be available to the European market. Currently, there has not been any announcements whether the lens will be available for the U.S. market. If Canon U.S.A. decides to sell the EF-M 11-22mm f/4-5.6 IS STM lens in the U.S market, a press release will be made on Canon's website, www.usa.canon.com
. The EOS-M System is still produced and supported by Canon U.S.A. and there is no indication that support is being discontinued in the near future.
Please let us know if we can be of any further assistance with your EOS-M. Thank you for choosing Canon.
