The Suite B news is ripe for confusion!
Suite B also includes AES, SHA-2, ECDH, and ECDSA.
None of which are being retired.
Mostly what's happening is a renaming of a bunch of stuff that was in Suite B to CNSA. It's still AES, ECDSA, SHA-2, etc.... but now with a shiny new name.
And for the record, I've not heard anyone (without their own tin foil hat) suggest that e.g. AES is nobbled.
