Right now, the way this is currently worded, every single foreign-made consumer router has already been pulled from the market, and has to request permission to be reintroduced. The only consumer routers not currently affected are those that are either already purchased (some good, but won't last forever) or are American-made (overpriced, underpowered dogshit)

From the news release "What does this mean?" section: "This update to the Covered List does not prohibit the import, sale, or use of any existing device models the FCC previously authorized."

So no, this does not pull all existing routers off the market. Anything that already got FCC approval remains approved and new stock may be imported and sold.
