It depends. If the assertion is that the customers targeted are a number of very high-profile companies and the US gov't, how often does either group refresh and then eventually sell off or recycle their surplus hardware publicly? I would expect, if this is true, a lot of the affected hardware to still be running for many years to come, and the majority of the private hardware to be disposed of in a recycling pile rather than showing up on the secondhand market. The government, as far as I know, does resell their used hardware sometimes in large lots, so perhaps some lucky customer cheaping out on buying hardware will find some exciting packets in their future...
