Beginning to sound like the winter of our discontent....
If this list has any legitimacy, and it probably doesn't, its origin probably answers questions.
If it's from the development area, winter 2011 may be the end of their involvement. From there, manufacturing process, tooling, etc. have to be set up. Production numbers have to be determined based on market analysis, etc., etc., etc.
It's possible the winter 2011 could simply be a typo. I often type 2011 when I mean to type 2012, especially this early in the year.
What's most probable to me is that it's a feeler from some marketing satan. They could honestly be looking for some customer feedback. Or it could be some low-level satan trying to build an argument for his pet project -- "look at all the comments that were made on the EF 60 L," he might end up saying. "I think they really want that."
Lastly, it could have nothing to do with Canon -- perhaps just a knowledgeable person with an interest in running traffic through this site.
So, there are a few grains of salt to throw on the snows of this winter!
