It could just be a simple reprint. A power button instead of an eject button makes much more sense seeing as Apple only sell 1 Mac with a disk drive. Maybe they didn't want to leave the F5 and F6 keys blank anymore so they stuck the backlight buttons on them in case you use your wireless keyboard with your MacBook open and wanted to use your keyboard to adjust the MacBook's keyboard lights. Adding backlighting to the wireless keyboard seems like a pretty big upgrade for a peripheral and will probably mean the battery life is terrible.
I've had my wireless keyboard and Trackpad since Boxing Day, I've changed the batteries in the Trackpad twice yet the keyboard is still reporting 100% battery life. I know that's to do with the way the keyboard uses an 'on-off' switch but Trackpads require constant power, but they don't need to make the battery life of the keyboard as bad as that of the Trackpad.
Also, a price reduction would be nice. £59 for a wireless keyboard is a little over-priced and no doubt they'll see backlighting as a reason to raise that to £79.
