That's largely correct yes thank you, Statement NG was primarily a substantial upgrade to the power supply section. However, a booster was also fitted to the main system, specifically for the processor for faster transients.Statement NG was just an upgrade to the power side of things, new AC/DC rectifier boards in the PSU box and new regulator boards in the server box.
Original PSU of Statement. 8 separate windings in the transformer going to 8 seperate AC/DC converters and each cable in to the server box has 4 seperate circuits.

In the NG modell the transformer is the same but the windings are connected 3+3 (2 windings are not used anymore) and only 2 rectifierboards and the cables has 4+4 wires for one voltage.

When the ZEN and ZENith NG was released with the new motherboard and GaN PSU regulators I was told that this would not be possible to do as an uppgrade to the Statement NG as the server box of the Statement was to small to fit these devices if that still is true I dont know.
The Nazare server might be the new "Statement" but there is a rather big jump in price from Statement NG to Nazare.
Regarding the Statement being eligible for a future upgrade to its mainboard, this is not something that is planned.
