A Google Engineer has confirmed that Ice Cream Sandwich, the follow-up to Android Gingerbread and Honeycomb, will indeed support both USB devices like gamepads and HDMI connectivity as well.
It doesn't come as a real surprise though and it does open the door to other prospects, like the ability to use a third party gamepad using an adaptor on any ICS compatible handset, such as the Samsung Galaxy Nexus.
There's even a fairly detailed tutorial on Reddit on how to set up a game controller for Android 4.0, which would convert your phone (or tablet) into a great game controller provided that you have the appropriate app and/or game emulator.
It is entirely possible that **someone** will come up with a cheap dedicated gaming console (or even a set top box or media player) based on Ice Cream Sandwich coupled with a powerful dual core ARM-based SoC.
It's also worth mentioning the comments of Sony's CEO who said that the company was in discussion with other handset manufacturers in order to expand the user base of its Playstation Suite to other devices.
Given that there are now more than 500,000 apps in the Android Market and that a fair few are actually games, it would make sense to push forward ICS as a potential gaming platform.
