more kalih switch boards
The length of time will be enough and people will begin to decide if Kailh are decent replacements for Cherry.
If not Gaote will take off.
Corsair RGB type systems will get more popular, but there will need to be a standardized API for programming effects.
It's too much to create fancy effects if you have to create them separately for a bunch of keyboards.
Also if RGB does start to take off, watch people program notifications in the keyboard eg you get email the numpad flashes red, a download finishes your spacebar flashes blue etc.
