I'm not sure that we've really ruled out one of the suspects. There still is the possibility that the FOXP2 gene found in Neanderthals introgressed from Humans, as argued, for example, by John Hawks and a recent article in Molecular Biology and Evolution by Graham Coop and colleagues.

I'm not all that sure that FOXP2 is all that central to language capability.

Consider Hawk's post:
http://johnhawks.net/weblog/fossils/middle/europe/atapuerca/gomez-olivencia-vertebral-canal-comment-2009.html

The references make two points of things that show up early in the fossil record: one is that the widening of the spine to take a larger spinal cord in order to control the diaphragm for speech; the other is the shape of the ear.

Both of these seem to me to be much solider evidence of the early existence of speech (as distinct from language)
