Possibly - but no one knows - there may be some new UA-themed offers once the merger sorts out. Or at least that's my hope!

Based on hope and vapor.
Timing might be tricky...for example, Mrs FTF has a CO business credit card, which is still new, and has never had the UA card. The trick will be when to try and switch her to the UA card via new application, before they probably rename all the CO cards as UA cards anyway, probably eliminating the chance to get a new UA card with a bonus. (Why don't we switch now? Just don't want to churn that fast considering all the other new accounts we've recently established.)
Anyway, long way around saying there may be offers again, but probably never again in the name of CO.
