Actually not that far off. The cladogram i presented was a little old. 
I've been incorporating lots of data I gathered from around the world
earlier this year (thats one of the problems of working with
prosauropods, the only continent that hasn't produced any is Australia -
which of course my home country :-( so one has to travel very far and
wide to see them).  I didn't finish this revision in time to include it
in the talk. Basically I'm now getting a small monophyletic
Prosauropoda, albeit one that excludes lots of taxa people might
consider prosauropods (taxa such as Saturnalia, Thecodontosaurus,
"Efraasia", Anchisaurus, Mussaurus, Yunnanosaurus, Melanorosaurus,
BlikanAsaurus) but I might add that it doesn't take much to bust it up.
Paul Upchurch says that he is now getting much less support for an all
inclusive Prosauropoda. Any way instead of duking it out we are planning
a large joint study, combining each others data. Consensus may yet be
acheived.
