The Regional deal is all but done, so I don't think IAG will have to worry about it. As for Baby, it seems as if things might be nearing conclusion too.
Though, as with anything in business, nothing is sorted until the money is in the bank. This goes for the IAG deal as well. All that's been signed is an SPA. This is the same as Regional. Many a deal has fallen apart later than that.
I'd be surprised if it happened, but it's not beyond the realms of possibility.
