To further explain real-world implications to those that aren't getting it:
I have dozens of clients that come to my studio to edit, and because there is no I/O monitoring, we literally cannot edit on Final Cut with them. The new program is useless to my business.
So, is I/O ever coming to Final Cut? If not, I can never use it, and I should start investing in new software/hardware and finding other employees. If it is, then when? 2 weeks? Six months? One year? Two years?
Ok, so I can continue to use Final Cut 7. They stopped selling it, but are they discontinuing support for it, like for new/evolving codecs? Will it work with Lion in a month?
Will Apple address these questions? If so, when? If not, why not? Other companies, like Adobe, give roadmaps.
All of these questions impact time and money - business.
All those questions are reasonable. Apple should really put out official word on these issues as soon as possible.
I'm pretty sure Final Cut 7 will work on Lion. I haven't tested but I don't see why it shouldn't.
