From the few official pictures of the Aluminium Apple Remote in 
Apple's Online Store, it doesn't look like there's a new, additional 
button. To me, it looks like they've simply moved down the play/pause 
button from the center into a new line with the Menu button. The 
photos also make me believe that the center of the navigation buttons 
is no longer clickable, so that the new Apple Remote, like the old 
one, has just six buttons - they're just rearranged.

That said, I didn't get a chance to buy a new Aluminium Apple Remote 
just yet and it looks like Apple won't make it available for purchase 
for a few additional weeks. Until then, I can only talk about my 
observations, not about first hand experience.

If you managed to get access to one of the new Aluminium Apple 
Remotes, please let me know.

Best regards,
