I'd say right now could be called winter 2011. As in, the northern hemisphere winter, which started end of 2011.
But those EF-S lenses have also left me a little head scratching.
EF-S 20-65 IS - If you make the BIG assumption of an EF-S compatible 1.3x crop sensor, the focal length would be about right for a standard zoom: 26-85 equiv.
EF-S 45-105 IS and EF-S 55-70 IS - could make sense as a prime alternative if made very fast, say constant f/2 or faster?
EF-S 70-400 IS - never saw the point of an EF-S long focal length lens, but if they make it cheap enough (perhaps half the 100-400L) I guess it could generate enough interest.
