Most of the uses of the Carbon framework in the Mac port are for Apple
Events and Carbon Events.  If the former is removed from the framework
in the near future, then Apple will provide some replacements in the
Cocoa framework beforehand or at least at the same time.  For the
latter, I don't think its removal would happen in the near future,
because Apple has added new types of Carbon Events even at the release
of the most recent version of Mac OS X (See
/System/Library/Frameworks/Carbon.framework/Frameworks/HIToolbox.framework/Headers/CarbonEvents.h
and search for 10.7).
