Windows Live Mail and Other "Live" Betas

There has already been sufficient coverage of the three Windows Live betas released yesterday. However, there is one comment that seems to be overlooked in all the postings. From the Windows Vista Team Blog:

"And, there will not be any graphical advertisements in Windows Live Mail at this time." {emphasis added}

So, if not "at this time", when and what kind of graphical advertiesments can we expect to find in Windows Live Mail?
