It makes me wonder how much extra stuff is pre-installed on the guitar itself.

The card holder is completely unprotected. It is asking to get broken.
At a minimum, everything is going to be wired to the card socket and not in a more traditional way. If that is all that they have done, you will be limited in the "personalities" that you can use. Over the long term, I would have some concerns about the connectors for the card getting dirty. It's an interesting concept, and I applaud them for trying something new, I just don't really see the value in it yet for me. When they get to the point where all of the controls are "socket-ed" or quick connect, things will really get interesting. Being able to pop out your tone knob and replace it with a TBX or clapton boost in as little time as swapping the card is when this stuff really gets interesting. Putting it on one model is putting a toe in the water to test customer reaction and the viability of the concept.There really shouldn't be any "extra" stuff in the guitar, as all the "wiring" is printed on the card's circuit board. The pups just plug into a connector instead of being soldered onto switches/pots.
While I personally will never own or use this system, I commend Fender for coming up with a unique & fairly practical product. I bet this would be pretty popular on their less expensive MIM strats. I can't imagine that it costs too much to implement when compared to standard wiring/soldering that has to be done by hand.
Don't modern Gibson guitars use a PCB in the control cavity?
As for Gibson, their PC Board is more about reducing assembly time than anything else.
