The IRS has said that they want to e-file 1040X and "hope" to have that running sometime later this "summer" To do that, the IRS must first write e-file specifications (schemas) for the 1040X and then program and test the IRS e-file system to accept the electronic forms, then give those specification to tax software companies to write and program their software. Then the whole thing must be tested end-to-end before released to the public. That procedure usually takes several months to do, and is still is the design stage.
