B&H has the new version II 11-16 on their site for 739. No actual information on the lens yet. I'm not sure how it will compare optically to the original, hopefully it's the same since I really don't want to upgrade. I know it has a new AF system which I really don't care about.
In theory it should have new coating that reduce flares. I recently started using Tokina 16-28 who is newer than 11-16 and so far it seems to me it flares less in pretty similar conditions, but I can't prove this scientifically.

Been thinking of replacing my 17-40 with the 16-28, we'll see though.
If you like the 11-16, you would love the 16-28 too. Great IQ, somewhat faster AF than the 11-16, great in low light. There is something special about these two lenses that is very hard for me to explain... They are just fun to use
Keep in mind the 16-28 can't accept filters that easily.
Glad to see Tokina still making great wide angle lenses. My Tokina 12-24 was my absolute favorite lens when I shot a crop Canon body...and I owned that lens longer than I think I've owned any other lens. Amazing build quality and great optics.
