Avid still is the top dog in Hollywood. According to a survey of ACE members (an honorary society of film editors) in 2008 80% were using Avid. It's still notable when a film is cut on FCP because the de facto standard is Avid when it comes to that level of production. FCP dominates places where the budgets aren't as big such as indie films and the prosumer market but they have made some inroads into the higher end of things. A couple of years ago, for example, 20th Century FOX started doing all of its in house movie editing on FCP. Avid and Adobe aren't standing still though and, IMO, have progressed a lot more over the past 3-4 years than Final Cut Studio has. Companies like Avid, Adobe, and Blackmagic are lighting it up at NAB this year and I don't know what Apple has planned for the next FCS update but it needs to be jaw dropping.
Personally I love all the competition and look forward to running Avid MC, FCP and maybe even PPro depending on what the situation calls for.

Prosumer market or not
Of course, Final Cut Pro isn’t the only product available for filmmakers, but it is the most popular now. according to market research firm SCRI International, Final Cut Pro has almost 50 percent market share in the nonlinear editor space, outperforming competitors like Avid.
