Wow this is some great deal! Just like you for myself I will wait for the II version, not because the version I is not good, but I just like to have the latest model. Totally emotional decision here. But anyone needing a 35mm prime, those are great deal no matter what the version II is (it will be more expensive and the verison I is already very good).
Maybe it is psychological, but I found that the L lenses that are a bit older like the 35mm and the 135mm do not have the same color rendition as some of the newer L series lenses, like the 24, 50, 85,or even the 70-200 2.8. Not sure if others have noticed that...
