July/August 2012
I am still being told by a couple of retailers that we'll see the new EF 24-70 f/2.8L II in late July or early August. Initial stock will be pretty good, though I do expect that all initial preorders won't be fulfilled with the first batch.
There is a bit of a shortage here in Canada on Canon lenses, there are lots of long running backorders. It does feel like Canon has allocated some manufacturing to the new lens(es) over the older stuff.
