Apple has recently made two filings with the FCC that show a new version of the Magic Mouse and its wireless keyboard.
The Magic Mouse will be called the Magic Mouse 2 and it doesn't seem to have changed much outwardly but the filings have only displayed the underside of the device, so that might change.
What is apparent is that the mouse will no longer need AA batteries but instead be rechargeable via USB.
As to the wireless keyboard, it looks to be sleeker, reminiscent of the thinner design of the new 12-inch Macbook.
When will these devices come out? Probably next month when new iMacs come out or a little later in the year in the leadup to Christmas shopping time.
