I am just speculating here, but could this be the reason for the delay? Maybe a new battery, let's call it 'battery 2.0' with better chemistry and who knows maybe the new slightly different format?
Musk announced that 1st cell will be produced in 2016, but there is a possibility that the cell be made in Japan by Panasonic, at least for the Model X, as a 'warm up' for their Gigafactory machinery? :)
OK, I am dreaming -- I just wish the model X will bring slightly more range, at least break the 300miles psychological barrier. That's just a 15% increase in battery capacity.
I think it is possible and that will bring a lot of customer delight that would definitely be worth the wait! :)
