No, but the article states that a "ground attack" version of an F-16 was cancled.  The reference clearly refers to a "close air support" version of the F-16 and not a "ground attack version", and I changed the article to reflect as such.  The irony is, even though this close air support version was cancled, the F-16 has engaged in close air support (CAS) in every major conflict (for the U.S.) it has flown in, up to and including present day operations in Iraq.  Your definition of ground attack is skewed.  Ground attack can be many things, including CAS, but also things such as interdiction, where high speed can be very much an advantage for a ground attack aircraft, to help avoid defenses.
