Besides Nintendo's Switch, where these could certainly come in handy for multiplayer titles with more than two gamers, the Bluetooth connection means they're also a very portable option for hardware controls for your smartphone. (Naturally, Windows PCs and Macs are also doable.)

Unfortunately, I could only handle dummy models here at E3, so any comments about how it feels are pretty moot right now. It's a little cramped, but it looks like it will be useable enough for Mario Kart and other games with relatively simple controls -- responsive Hadouken input still TBC. I'm hopeful I'll get to test one out for real before the selection goes on sale later this year -- and hopefully the price tag will appear, too.
