Why would ever LM13700 disappear?
It's the cheapest OTA with thousands of uses.
Just like TL0x, LM324, NE5532, LM2902 and other ancient designs it's not 
going anywhere simply because it's cheap, and for decades used by large 
companies in mass market products.
While I was observing LM13700 availability recently, there was none, 
then there was over 100.000, now there's 45.000, only a few days apart, 
so obviously someone is buying them all the time in big quantities. Not 
as big as NE5532 but still a lot.
