Homo timoriensis and Homo celebesiensis?

Homo floresiensis, the hobbit of Flores, is still debated as to whether it is a distinct species or not (or even a new GENUS as proposed by Dr. Dwight Smith and Gary Mangiacopra). But soon a new excavation will take place on other localized islands around Flores.

Mike Morwood is predicting new hominid species may be discovered on the islands of Timor and Sulawesi. Going to the level of proposing some may be found to be dwarf like, as on Flores, or gigantic in stature.

Are we perhaps in the near future to open even more debate over new hominid species?
