FCPX will also require a nice update too. The Pro's that have tried it won't give FCPX a second chance until the required functionality is added back again. Googling "missing FCPX features".
( BTW - I don't want to bucket all Pros into a single group, some Pros are happy with the existing functionality, while others need the functionality that is in FCP 7 but isn't in X ).
true, which apple has already addressed some of those missing features. i think some things, like saving to tape, isn't coming to FCPX
