Berlin to Munich is pretty fast. The issue with Berlin-Paris is that you have to go through NRW, which is where German trains go to get slow and delayed.
The direct route would be through NRW, but the one this train takes is going further south via Erfurt-Frankfurt-Strasbourg. Strasbourg has a proper hsr on the French site, which helps a lot. It technically would be faster to go via Cologne and Brussels, but that would cause a lot of problems.
For the current route the big missing section is between Mannheim-Frankfurt-Erfurt. There are plans for it, which are being pushed right now.

Makes sense. I was thinking of the old non-direct route.
