A collection of EM's Tweets, collected at the link below, provide some post-reveal details on the model X rollout.
Sounds like it may not be until ~2017 (if ever) when Tesla will begin deliveries of model Xs at a price much below $100,000.00:
Lower-Range Model X Will Be Built... Someday
One of the hottest topics of concern and speculation has been whether or not Tesla will offer a lower-range Model X using a 70 kWh battery, or something similar - rather than just the 90D and P90D versions currently rated by the EPA. It seemed that was confirmed when Elon recently tweeted that lower-cost versions were planned, but it wasn’t super explicit (what size battery? when?). We still don’t have all the details, but it seems the details aren’t worked out yet. What we do now know is that it will be ~70 kWh ("something like a 70") and the estimated time of arrival is ~12 months from now.
We won’t start talking about "Tesla time" and all of that, but ~12 months is perhaps when long-term X reservations will finally be under control a bit (there are currently ~30,000), so perhaps Tesla is just holding off until these higher-priced, higher-margin Xs are not in such high demand. Or perhaps Tesla wants to achieve some battery improvements before rolling these Xs out. Anyhow, here’s the tweet:

Lots of comments on the Tesla forum RE the unconventional
utility aspects of this "Sports Utility Vehicle", many focusing on the second row seats
(less cargo space than the model S...will they ever fold down?) and living with the
Falcon Wing doors.

I expect Tesla will fix the seat problem, eventually.
The FW doors are another matter, as they are promoted as the Xs signature feature, and it's unlikely (IMO) Tesla will give them up.
I'm not convinced their advantages outweigh their disadvantages, as opposed to conventional sliding or hinged doors, at least for many potential buyers.
I live in an area where extreme winter weather is common (well, it
used to be common, until ~2012...) of very heavy rain and snow events, often concurring with high winds.
So, the way the FWs expose the interior to precipitation, especially for the extended time while the doors slowly open and close, would probably be a problem for buyers in similar climates.
For most X buyers in mild climate, the only real disadvantage to FW doors may be
IF they turn out to not be highly reliable, which will probably remain unknown until many Xs are on the road, for an extended period of time.
Given the complexity of the FW design, the multiple factors that could lead to a door failing to open (or worse, failing to close, rendering the X ~un-drivable) would give me pause, even if I was in the market for a ~100,000 SUV,
which I certainly am not.
