It's always nice to get a newer better wifi standard but in this case I think the naming convention is the best ideaa.

The new standard will be known as Wifi 6. The current top of the line (802.11ac) becomes Wifi 5, 802.11n becomes Wifi 4. Makes total sense. It's optional but I can't imagine everyone adapting that.
