It's not "just" a shortage of GPU's but all kinds of components.
And it's also not "just" caused by miners.
But that means if they are really unlucky they could launch into a situation where there is a surplus of good second hand graphic cards and still shortages/price hikes on the GPU components they use...
Through as far as I can tell they are more targeting OEM's (any OEM instead of a selected few), and other large customers, so it might not matter too much for them for this release (but probably from the next one after one-ward it would).
