Don't know if this was posted yet. I have a source that tells me that the new controllers bundled with the slim will take AA rechargeables batteries, and these batteries will be able to be charged via the controller through microUSB to the console.
All "buttons" are now capacitive touch like the original PS3 eject (except for the wireless sync button).
Pretty sure it was said that the old drives don't work in this revision since it's a new form factor.
Dedicated port for Kinect as on legacy consoles you'll have to use a breakout with usb port/power connection. I will assume that this has been posted

The AUX port is the dedicated Kinect port.
Also, there is still an external power brick for the slim but it is tiny in comparison to the original.
Sorry if any of this is already posted. Source is definitely reliable so these are all fact.
