Read all about it here, along with picks past and upcoming. (and if you're interested in 'the process', the research was done here)
Meanwhile, KC Johnson is putting out the idea that the Bulls are trying to package their pick to create more cap space. I don't quite get how that type of deal works right now with no teams actually able to use their cap space until 7/1...but maybe that's just something that can be agreed to, with the Bulls effectively drafting for another team. I find it hard to believe that a team with cap space would take away the chance at playing the FA market themselves to take a Bulls contract.
And similarly, I wouldn't get the Bulls rush in moving either Deng or Hinrich for cap space, unless they knew they're getting two big FAs.
