Blog suggested 1st "early-bird" release of SF2.0 will be out in a few wks, typically that means the final release is just a wk or 2 later.
I doubt they're shipping end of July, but August certainly seems quite doable, or maybe they'll ship end of July with a rough build, & send the final build later (doubtful).
