Gee, all that rooting around so you don't have to worry about FireWire. Sure hope you don't discover a lost box of tapes in a few years time.
Considering camera video was Mr Jobs poster child for the elimination of FireWire - not much of an advertisement.
I think my point, is that if you have gone tapeless for new footage (and I have) now is a great time to bring all your tapes onto a drive, and give that old footage the same accessibility, flexibility and backup options as the new file based formats give you. Use your
existing machine (that has firewire), and a cheap, huge drive, and be ready for whatever happens going forward.
I did all this so I could (re) discover footage I have not had time to look at since I shot it and chucked it in a box - there are now no more tapes to discover, I made sure I got it all, and I now shoot tapeless - which eventually, everyone will too, from the super pro's shooting 4K HD uncompressed direct to RAID (e.g. RED ONE), to pro's shooting to P2's flash cards, to consumers like me shooting 25mbit/sec AVCHD to SDHC cards.
There are devices that can record digital tape (DV, HDV) to disk (Sony make one) and then you can mount that HDD, and use ClipWrap to create .mov's - so it would not be impossible to get tapes onto a firewire-less computer, just rather inconvenient and expensive!
However, once you have files, the internal formats just become a software problem, you no longer need to worry about keeping the physical media intact, and devices to read them working. Just keep copying the files. (TimeMachine, Mozy etc. etc.)
Like you, I really hope they put Firewire back onto the MacBook, or better still, put ExpressCard/34 onto all their computers and then we can add whatever interfaces we each need, I would like eSata on an iMac, for instance. (Or any machine other than the MacPro, for that matter)
I think it was too soon to lose firewire, but then people said that about the 1998 iMac not having a floppy disk drive, and only having USB and FireWire instead of Serial, Parallel and SCSI, and that bold move prompted a shift away from legacy ports for the entire computing and peripheral industry.
