Future upgrading from current MBP express card 34 capability to54 possible?

Question

My MBP arrived this morning and (my bad) I just noticed lack of FW800 port. I came here to discussions before tearing the seal on the protective envelope in case I might need to return based on your answers:
From reading here, I see people saying express card is better than FW800, but saying 34 is bad, 54 is good/wave of the future.
If I keep this MBP, will I be able to have the internal 34 upgraded to 54, or is the physical slot opening in the body unable to do this, making this MPB already obsolete?
And assuming that there is eventually an expressCard34 adapter eventually made for FW800 (current links provided on the board only led to expressCard54 adapters to FW800), will I be getting FW800 speed (or faster)?
Sorry if these are dumb questions.

Answer 1

ExpressCard 54 cards are wider than 34's (hence the name), so no, the slot on a MacBook can't support them. It's possible someone will come out with an adapter with some kind of a dongle that plugs into the 34 slot, but it would be cumbersome to use.
When a FW800 ExpressCard 34 comes out, it should be full FW800 speed, since the ExpressCard bus speed exceeds the speed of FW800. But you'll have to check the individual card vendors to see what they provide on their products.
