Xtol appears to be out of stock everywhere, and B&H is listing it as "discontinued."
I queried B&H by email and got a reply that, "Our buyer says he doesn’t expect to see Kodak brand Xtol ever again." Now, whether this means that there will be Champion brand Xtol or something else, that is completely unclear. Kodak sold off their photochemistry division to Champion some years ago, so the Kodak labeled Xtol hasn't actually been made by Kodak for quite some time. You would think that would also mean it would be unaffected by the bankruptcy.
Unknown to me (until today) was the fact that Freestyle distributes an Xtol clone under the LegacyPro brand (formerly Kentmere I believe).
I just ordered 5 packages to be sure I'm covered in the short term at least.
