I'm going to throw this out there as a quick conspiracy theory. While no one is leaking this information, it's possible that Wade/Bosh or LeBron/Bosh are waiting for Wednesday to see where the salary cap number falls.
Why is that important?
A number around 57 million gives the Bulls two maxes without moving Loul Deng. A number of 56.5 million gives them 2 maxes if one guy comes in a S&T.
The number might make a large difference in the type of package the Bulls can put together in terms of luring multiple players.
