"Will consumers will wait for wi-fi 7 ...?"
"Oh yes they will"
"Oh no they won't"
If Wi-fi 7 is delayed for any reason, governments can sell spectrum for 6E, manufacturers can sell 6E equipment and everyone is making money.
When the delays for 7 are overcome, governments can sell spectrum for 7, manufacturers can sell 7 equipment and everyone is making money ... and thus the ball collects moss until 8 is ratified ...
