Is there any information on the range of the Model X? I cannot seem to find it anywhere.
Are there different range models?
Tesla was explicit that they plan to use the same battery packs as for Model S (except for the 40kWh variant), see the bottom of this page: http://www.teslamotors.com/modelx
The specified range for the Model S for these packs is 230 miles and 300 miles, respectively. The specification is based on a constant speed of 55 mph, thus it is (and must be) somewhat artificial. Based on experience with the Roadster, Tesla's specified ranges should be meaningful and actually achievable in practice, but YMMV.
For the Model X it was stated that ranges will go down approx. 12% by comparison with the Model S, due to greater weight and frontal area (greater aerodynamic drag). That would be 200 miles and 260 miles respectively. It seems to be implied that the difference in range between RWD and AWD is negligible, but I have not yet seen any explicit statements.
Has the MS range or performance been reduced by the frigid temps in the North-Mid-Atlantic states?
Yes, just like ICE cars, range, performance and efficiency is reduced in very cold temperatures.

On another thread, you indicated the Tesla battery temperature was regulated, implying that there was no direct effect of the environmental temperatures on the battery itself.
Is that implication correct? Does it not mean the effect of cold temperatures is just the effect on the workload and, perhaps, on the efficiency of the motors?
@Remnant - You're reading more into the answers I gave to the questions you asked. In the other thread, you stated that Tesla should have a battery warmer, it does (and a cooler as well). Above you asked if range or performance was reduced in the cold temperatures, they are.
What you didn't ask was if the cold had a direct effect on reducing battery performance. ;-)
I believe it's a combination of both the increased workload (colder, denser air, more rolling resistance on snow, etc.) as well as the fact that all heating to keep the batteries regulated must come from either the electricity coming from the connection to the grid if parked (and I'm assuming plugged in) or from the batteries themselves or motor while moving. This will undoubtedly have an effect on range just like in an ICE car of about 20%.
Here is some more great reading for this...
