We also got a look at the Pro Mini controllers for Xbox 360 and PS3, which are pretty much exactly what they sound like. Both the wired Xbox and wireless PS3 version feature small form factors, reversed analog sticks and LED buttons. Of course, the stock controllers on either system aren't exactly huge, so your mileage will vary.
Next up were new Air Flo controllers for 360 and PS3. Both Air Flo controllers are wired, though for good reason: Each controller comes packing an internal fan to cool your overheated digits. It might sound silly, but the cooling effect was pretty remarkable. Those with sweaty hand syndrome should definitely take note.
Finally, we saw a handful of 3DS accessories. The first was a snap-on battery pack capable of doubling the 3DS battery life (according to Power A's John Moore). Power A also revealed a trio of new 3DS audio accessories, including an over-ear headset with detachable boom mic, earbuds with an inline microphone and a speaker stand with a drawer for cartridge storage.
All of the Power A products on display at E3 should be available this year.
