This new information is the major reason for my post. The control is now far superior if the recent reports are accurate.
The actual operating temperature of the core internally is not different unless it can now be elevated without danger of thermal run away, and if the process is totally under control of something as simple as an electric current then he has a much improved device.

Water flow was increased to retard the reaction, and conversely water flow was retarded to increase the reaction. On the other hand, the DGT core is also thermionic. DGT turns the reaction off and on to produce a pulsed heat source where heat generation is averaged over a period of time. Because the reaction mechanism is no longer thermionic, there is no coolant involved, electric control alone can regulate the reaction in the E-Cat core. In the new solid state E-Cat design,a steady flow of input electric current results in a steady level of direct output of heat production. The elimination of thermionic control is major progress made possible by the design of the solid state E-Cat, IMHO.

When Rossi presented the ecat in Jan 2011, he said the core would reach temperatures around 600C, but the heated water only just boiled. Now he claims the core is stable at 600C but he is not doing anything with the generated heat. Is this progress or puffery?
