will apple put the air in macbook air?

In all of the rumors and speculation about tomorrow's Apple announcement and new Macbook Airs, I'm surprised by something. In all of the discussion re. hardware, there's been nothing mentioned about an integrated wireless modem. An 11.6" MacBook Air with an integrated 3G modem would be an interesting addition to the product & price point line up.  Has the rumor / leak mill just missed this one, or does that veer too close to iPad land?
