So I was listening to one of the more recent Bombcasts the other day, and the crew were talking about how the 360 controller might change with the next generation of the console. Given that they have already laid the groundwork for a companion touchscreen with Smartglass, I wouldn't be surprised if they incorporated this into their next controller. This was more or less said on the bombcast, but concerns were raised over how changing such a popular controller might affect the fan-base. I think there is an obvious solution.
Use the space that you would normally put a chat pad, and fill it with a small (phone sized?) touch screen. It could even act as a chat pad still since most people are fairly comfortable typing on a touch screen these days. Thoughts?
