Like I said a few posts above, you shouldn't worry about that. Just for the classic Marvel 'Conan the Barbarian' title, about a dozen Omnis will be needed, so definitely not a short publishing window like in the Shang Chi case. At all. AND they're now publishing their own new stuff, so Conan is not going anywhere anytime soon.
That's right. That's why all three are so sought-after, especially the first one, published many years ago.
They're actually doing it now: Conan Chronicles Epic Collection.
