I must say, I was pretty blindsided by the 8-15L and 70-300L announcements. There were hints at CanonRumors about a revised 70-300 but no one thought it would be an L. While the fisheye zoom does not interest me, I will keep an eye on the 70-300L reviews.
Otherwise, I can't help but feel that Canon has abandoned the non-L EF line. They have left it to wither and die. I personally was hoping for some non-L EF prime announcements, mainly a EF 35 1.8 USM and EF 50 1.4 USM II.
Oh well. Along with those hoping for a 24-70 2.8L IS, I will continue to wait and be patient.
