As mentioned elsewhere, this key will be required as a part of the standard Windows keyboard layout. This is not true of other recent keys (emoji, office, etc.).
Apparently they didn’t push the Cortana key either. And they say it will “eventually” be required. As a keyboard manufacturer why would I listen to Microsoft? Why would I add a key that supports a product I see no benefit from? Just so I can trend even though my customers don’t want it?
I ask because this makes the “Microsoft is going to require it so the other keys don’t count” argument useless. Who cares what Microsoft requires for their own hardware?

As a keyboard manufacturer, you don't have to see any benefit from the product you support. The question is only will the incremental costs be more than offset by the incremental gains in sales. If MS requires the key, that's 90% of the market (really rough number), so it makes sense to add it. If MS and your competitors add it, it may make a significant percent of your customers go elsewhere. Even if they don't want the key, just because they think your keyboards are old.
Ah so aggressive keyboard trendsetters control the market then. It’s more likely that these keyboards will be a rarity. And when people see a keyboard with this key in a few years they’ll think, “what a weird old keyboard you have”.
