Here is the answer from AVM:
Good day,
Thank you for your inquiry and your interest in our products.
You’re right, the FRITZ!Box 5690 Pro and the FRITZ!Box 5690 XGS have been announced for a long time (since the beginning of 2023).
The FRITZ!Box 5690 Pro will probably start in June / July. The FRITZ!Box 5690 XGS will also follow, but there is no specific date or date for the market launch yet. The proportion of XGS-PON connections is very small in Germany.
All known information about the FRITZ!Box 5690 XGS can be found here:

Unfortunately, further information about the specific market launch is not yet available.
