Stepping back a minute...
The last decade has seen nearly every hospitality company that owns a timeshare business spin it out into a separate company. The idea behind this is that the companies are better able to build market capitalization (i.e. more money for the shareholders) separately than they are together. I don't know why this is, but it's noticeable. Marriott did this about ten years ago. Hilton and Wyndham both did sometime in 2017. Bluegreen has always been independent (and public) while Westgate has always been independent (and private). That leaves just IHG (Holiday Inn Vacations Club) and Disney as the lone holdouts of the major players.
So,
if there is anything behind this, it could just be a spin-out as a stock price manipulation move.
There has also been significant consolidation in the timeshare industry over more or less the same period. Some of this consolidation has also merged the systems; other combinations keep the systems separate, but take advantage of economies of scale in management, marketing, etc. Marriott has added Sheraton and Hyatt. They've stated they plan to fold Sheraton/Vistana into Marriott Vacation Club (just as they already have on the hotel side), but they plan to keep Hyatt separate. Wyndham has added WorldMark and Shell. WorldMark is (and for complicated reasons probably always will be) a separate system, but Shell is being absorbed into Wyndham. Diamond spent the last decade acquiring a bunch of different resorts and smaller resort networks merging them into The Club, but has since been acquired by Hilton. Hilton has been open about creating a two-tier system, with their existing resorts (Hilton
Grand Vacation Club) as the top tier, and some (but not all) of the Diamond resorts as the second tier (Hilton Vacation Club,
sans Grand). Holiday Inn VC has acquired Silverleaf, and added it to its existing system.
So, it is also possible that
DVC would sell the brand off to someone else. That someone else could manage as a separate entity (as Marriott does with Hyatt and Wyndham does with WorldMark) or combine it into an existing system.
If I was the CFO at TWDC, I'd think it would be near-malfeasance if I didn't have someone periodically asking: "Should we spin out or sell <business X>?" for just about any business I ran. That's not because I wanted to sell off X, but it's because I need to always know what my options are. Answering those questions almost certainly requires talking to people outside the company to get an idea of valuations, etc. So, it's also entirely possible that (a) these conversations happened and were overheard but (b) they don't mean anything at all in terms of intent.
That's because all of these questions get filtered through company strategy and culture. And Disney is not currently a company that spins out or sells businesses. Instead, they have been near-fanatical about trying to acquire other brands and businesses that have synergy with things they already own, relying on the network effect to increase value across the portfolio. If I were to place bets about how consolidation works with respect to the DVC portfolio, I could see Disney acquiring a small, aspirational brand and using BVTC to make exchanging between them easy. But, I'm not sure which if any of those are still independent, so the opportunity for that has probably passed.
