Unlikely, but ambient visual notification is on my wishlist as well.

If Apple does implement it, my guess is a single-color, white LED backlighting the roundrect label on the home button. "Pulse home button" becomes an additional on/off switch for each app's notifications in Notification Center.

Apple does have patents for it already: http://www.patentlyapple.com/patently-apple/2011/04/apple-bl...

So it's not entirely out of the question.
