There are no post-quantum proposals from the NSA anywhere in sight
however, right?  

Is it possible they have post-quantum algorithms they wish to remain
classified, like particular arguments for choosing key sizes for just
Ring-LWE DH?  Yet, they need a public announcement like this to shut
down government contractors currently building products based upon ECC.
In that scenario, they do not really need any attacks on ECC beyond
Shor's algorithm.  There might even be money to be made choosing what
contractors get to use the post-quantum algorithms.

Just another fun conspiracy theory :  They dislike that small key sizes
encourage people to use a *lot* of crypto, maybe including the long
-term forward-secrecy found in Axolotl based system.  Axolotl becomes
as strong as a deterministic one-time pad if they miss the wrong
message.
