The deal is done as far as WBD and N are concerned. Offer accepted. Many previous meetings. Contractual obligations are now in place while approval is pending requiring WBD to continue as is, with limits on spending for new projects.Typically they should have visited BEFORE they agreed to acquire the Studio, not after. Given that press was there this is yet another PR spin to make it look like they have it in the bag. And maybe they do, but after the acquisition process begins you typically don't have CEOs doing a site visit as you want to keep the impression of impropriety out of the situation, ie they have to continue to be run separately until the acquisition is completed, you don't want it looking like Ted there is trying to make decisions before they fully have the Studio. For example Iger didn't visit the 20th Century lot during the acquisition phase, and certainly didn't do it until AFTER the 21st Century shareholders approved the merger and it passed regulatory. In fact I can't remember any CEO of any recent merger doing a site visit prior to it closing, but I could be misremembering.
The doesn't seem odd, nefarious, or a breach in protocol to me.
