Here goes nothing:

Revised theropod phylogeny, based on the work of Sereno, with suggestions 
and elaborations by Pharris ;-) and Holtz (Dinogeorge, you're not going 
to like this much):

Theropoda
   Coelophysidae
   Ceratosauria
      Ceratosauridae

            Carcharodontosauridae
         Coelurosauria
            Ornitholestidae (a near-perfect intermediate between 
                        allosauroids and dromaeosaurs)

                        Archaeornithoididae
                  Euaves ("true birds"; _Sinornis_ to modern birds; I am 
                                looking for a comprehensive classification of 
                                euavians, to be included in future theropod 
                                classifications)

As I mentioned the last time I posted this classification, _Avimimus_ may 
be either a paravian or a euavian, and troodontoids may be more closely 
related to euavians than tyrannosauroids.
