The chipsets for WLAN 6e are still very expensive.
An internet box with it will probably come first. That's my gut feeling. A little later, then probably the corresponding Wifi box with Wifi 6e.
6e is meaningless in Europe. The possible spectrum is severely limited compared to other countries. It needs more antennas and even more effort to separate the bands cleanly. Added value is probably zero at the moment. I would not expect 6e to be built into a Swisscom product in the foreseeable future.
The WB2 with Wifi6 is easily sufficient for the next few years. Even today, not all new devices support Wifi6 because the chipset and effort are massively more costly.
