Interesting times we live in.
FCP/FCS has pushed hard to make major inroads into the mainstream broadcast industry. I'm sure broadcasters aren't the majority of FCP customers, but they do provide leverage and confirm that the product is "professional" by using it.
FCP 6 and 7 have made massive inroads and displaced Avid in many areas, particularly those transitioning from SD and entirely standalone/tape-based workflows to HD and more hybrid networked/tape+tape less workflows.
FCPX appears to be version 1 of a new editing app. Massively more powerful internally, with lots of stuff that was all-too-obviously missing from FCP 7 (and FCS). Stuff like 64 bit processor support, background rendering etc. It's at a great price point, and as a domestic consumer it looks great as an HD-friendly replacement for FCE (and massively better than iMovie)
HOWEVER - FCP X is not currently a full replacement for FCP 7 installations as used in many broadcast areas. The limitations on core workflow support mean you just can't consider using it - and most broadcasters wouldn't want to use such a new product today.
If you are a broadcaster building a new operation - what do you do? If you are an existing post house wanting to expand with extra FCP / FCS suites - what do you do?
You can't buy FCP 7 / FCS any more. Apple won't sell it to you.
You can't use FCP X - because it has zilch support for workflows that you can't work without.
The criticism of FCP X has got a bit harsh and heated - it's a version 1 product. I can cut it some slack. (Though there are some jaw dropping omissions - I can see how Apple can see that a large proportion of FCP users - mainly self-contained, small scale producers and those making movies for fun or for education.) It's a new product built from the ground up, just like Mac OS X was a new OS built from the ground up.
What I can't understand is how Apple think they can pull the plug on the previous version, when the new version has so much functionality that is vital to a proportion of users (who may be a minority, but they are influential, add credibility AND use FCP to generate revenue - and buzz about the product)
Many of the supporters of FCP X have posted that people should stop whining : "They can carry on using FCP 7".
Sure you can - but only if you have it already...
What do you do, today, if you need to put 50 FCP seats in a new broadcast centre?
What do you do today, if you want to put in more edit suites into your facility?
You can't use FCP X - it won't work in many broadcast and post-situations that FCP 7/FCS is fine in. You can't buy new versions of FCP 7 / FCS (unless you can find them on a shelf somewhere)
Effectively the FCP market has been thrown into limbo.
Seriously - what do Apple think people are going to do in the next 6-12 months minimum it will take for FCP X to gain the internal and 3rd-party functionality needed to replicate current FCP 7 workflow?
Avid, Adobe and even GVG, Sony and Quantel must think Christmas has come 6 months early. (And I can see some people looking at Lightworks anew as well)
I wouldn't be at all surprised if Apple released a "We've listened to our customers, and have decided to allow FCP 7 / FCS to be purchased for an interim period" If not this could be MobileMe v2.
