The timetable for ÖBB's nightjet service from Paris to Berlin (and vice versa, from 11 December, three times a week) is now up on the Nightjet website
https://www.nightjet.com/. Unfortunately they're still failing to live up to the bicycle-friendliness of the old CNL routes they replace, and bikes can't be taken unless packed up on the Berlin-Paris route.
(For a list of routes they do take bikes on see here:
https://www.nightjet.com/en/angebote/fahrradmitnahme - basically just between Austria, Germany and Switzerland, albeit not the route from Berlin to Vienna that goes via Poland - if that's even running still).
A real shame - I was looking forward to this route being reopened to sleeper trains, but since both Eurostar and Nightjet are both pernickity when it comes to bikes this new-old route isn't much use to me
