I read around here somewhere that the Model X second row would have turning and moving seats to make entry much more accessible. So you don't pick up the kids hurt your back or something, they move and turn for the exit? Would be sort of weird and gimmicky but not weirder than Falcon wing doors I guess. Elon's "They're the best second row seats you've ever seen in any car ever" comment from yesterday's earnings call kind of also goes in that direction. I don't think he would mention just design aspects as something that would be responsible for the X's delay. ( I believe he said the falcon wing doors and the second row were the "adventures" things responsible for the delay )
However I don't think that fancy electronic moving second row seats would be the reason they'll keep the car from being shown before deliveries. I doubt that they'll hold a private event for early reservation holders, probably Elon played with the wording there as they won't show them in "auto shows" If not, there's definitely something that would cannibalise Model S demand. If there is, that cannibalisation will happen regardless since they'll reveal it with the first deliveries in the summer and then people will order like crazy and they won't have the capacity to build them.
