Hello. What is it about the current Mbox that doesn't 'cut it' as you say, but a Firewire version would? They won't offer any more inputs. Their lower offering has always been 2 stereo in and out plus SPDIF, no MIDI. AMIII card as an example. So they wouldn't add any of that. What's your issue with the current USB? As for Tiger, it is slated for release around June '05. However, applications won't be ready for it for a while after that. They are almost never ready when a new Mac OS is released. Pro Tools has never been before, so why should it be now. So a Pro Tools version that would be Tiger compatible is probably at least a year away, for AES New York in October '05. And if Tiger is delayed in any way, well you know. Pro Tools 7.0 is supposed to be released by Summer NAMM '05.
