The problem in my case is that we usually have to setup additional editing bays during the year, since business has been growing, it’s impossible to install a legal version of Final Cut Pro 7 on a new machine since Apple stopped selling it. The new version is awesome, but without these 10 features, it’s impossible to be used in a professional environment. Regarding the legacy format compatibility, there is nothing to do with the application being 64-bit, since .fcp is a XML derivative, it’s not that hard for Apple to create an import tool in order to migrate old projects.
They have created a real problem for users and companies who live on the software, and the least they could do is supper us on the transition, that’s all.
