Is it me or it is just a statement of good intentions with little actual data? I feel like they have a lot of people that really want to show all the details, but the old communist party information denial by default gets in the way.

You are certainly correct. Lack of transparency is a common problem among all Chinese space related projects - might they just don't know how to present information to the general public.

At least one misprint:
the line "Beidou-2 I4 retires in Nov 2019"
should read
"Beidou-2 I5 retires in Nov 2019"

Do I understand this list correctly that they will keep replacing all the GEO and IGSO satellites even after the MEO satellites are in place ?

Has anyone any information on how big a difference the availabilty of these satellites will make to the quality of Beidou derived positions at that time ?

Yes, 10 years ago the final Beidou constellation was planned to include by 2020 35 satellites: 5GEO 3 IGSO and 27 MEO

I found it on the above link. No idea how this (confidential information, at least in the eyes of Chinese government) leaked out. I think the information is credible except the misprint you have pointed out.

Keep improving the continuous stability and service accuracy of the BeiDou System, and will launch 2 BeiDou-2 backup satellites in 2018, ensuring its regional service performance maintain stable and grow better.
2 Push forward the research, development and construction of BeiDou-3 system.
In 2017, it is planned to launch 6 to 8 BeiDou-3 MEO satellites
In 2018, about 10 BeiDou-3 MEO satellites and 1 BeiDou-3 GEO satellite will be launched
From 2019 to 2020, 6 BeiDou-3 MEO satellites, 3 BeiDou-3 IGSO satellites and 2 BeiDou-3 GEO satellites will be launched

China's navigation system gets powerful chip to improve positioning
Quote
BEIJING: A new powerful chip technology has been introduced in China's national satellite navigation system to provide high-precision positioning.
The chip, which will be attached to the satellites of BeiDou Navigation Satellite System, was unveiled by the Global Navigation Satellite System and Location Based Service (GNSS & LBS) Association of China (GLAC).
The positioning accuracy of the chip reaches at sub-metre level without ground-based augmentation, state-run Xinhua news agency reported.
The chip, developed by Shenzhen-based Allystar Technology, has been earlier used in unmanned driving systems, wearable devices, precision agriculture and smart logistics.
The chip supports the new generation of BDS-3 satellites for high-precision navigation and positioning, the report said.
Besides navigation, China also uses BDS for its military applications to avoid dependence on America's Global Positioning System (GPS).
