It's not just a rumour, and it's not Intel-only. Several parts of  
Carbon will not be 64 bit under Mac OS X 10.5. See the "64-bit  
Carbon" and "Is Carbon Viable?" threads at
http://lists.apple.com/archives/carbon-dev/2007/Jun/thrd3.html

(and on the following pages)

In particular the messages from Eric Schlegel (he's from Apple), e.g.

Nobody can say how likely that is. It definitely won't happen in the  
near future, since there are a lot of Carbon apps out there.

Yes, it is (just as practical to do the logic in C or C++).
