Hi @BlakeRichardson . Knowing that we are both in New Zealand, I'll speak from the NZ perspective.
The wait time is affected by the components being used in the device (thanks to chipageddon). For example, MX67s are unaffected and ship normally. However, the MV72X is badly affected and can take 3 months to get (it's affected by the shortage of SSD drives - 512GB SSDs I think - not 100% sure). MV12 seems to be shipping normally (it uses a 256GB SSD). MX84s can be particularly hard to get. MR32s are very hard to get (but hopefully not one is buying those still).
If some devices are more important, split your order in two. For example, order all your switches on one order, and the MVs on another. Then a product shortage in one won't delay the other.
I'm not aware of any shipping issues with regard to any of the MS family.
