Okay, a bit of reading tells me this: this is the company that's been "refurbishing" DMC vehicles since they bought the rest of the company's spare parts stock in the 1980's (I may be off with that timeline, but I think that was right). They have enough in the way of "spare parts" to build about 300 new cars - at a cost of just under $100k each.
The reason they couldn't do it before is twofold: first, John Z's widow was in a huge lawsuit with them about using her hubby's name. It appears that has been resolved. Second, the NHTSA changed the legislation for vehicle makers who produced under 500 units a year ("Low Volume Motor Vehicle Manufacturers Act", H.R. 2675). Since the Delorean meets the criteria of being a vehicle older than 25 years, they're now free to build the units from stock. They do have to meet EPA and NHTSA standards - though not the same as GM, Ford, Chrysler or Toyota would have to.
Now the problem: determining what kind of powertrain to put in the thing. What I've heard through Jalopnik is the possibility of a Toyota V6, but a GM engine is also possible. I suspect that is what they're going to do over this year: see what works, then negotiate the purchase of 300-some engines.
The real fun comes in late 2017-18, when they run out of their original 1983 stock...
