I know some first hand information from my Dad: he has friends who know well HKSKH's developments. They are trying to get someone a bit younger to be the new Primate, and this is why the current bishops of the three dioceses are not elected - all are around 60.
As far as I have heard, the new one seems to be even more orthodox/"conservative" than Peter Kwong, whom my parents personally know. Peter Kwong has an unfortunate habit of accommodation with the liberal "Christians" at times even if no liberal himself. Sometimes he dabbles into social gospel, but not much, and very mild by anywhere's standards.
The new Arshbishop is flat out evangelical, however.
Thank you for the information!
