I had always thought Disney could ROFR for any change on the title. So if you and your spouse was listed, there was a divorce, you won the contract in the war, got remarried, and wanted to add your new spouse to the contract, Disney could technically take the contract when you tried to change the title. Not that they would do this, but it was my limited understanding of the ROFR.
I would think if a contract was purchased on the steps of the courthouse, they could ROFR when you tried to change the title. I don't think it's the smartest way to buy a contract, but I could see the TTS doing this as they would know the ends and outs of the ROFR.
Back to the original subject, I think a few things are going to happen with DVC prices over the next 10 to 15 years:
1) Yes they will dip a bit while the economy is down, but on a 100 point contract, this is only $100 savings on every per point decrease. You'd still be paying around $8,000 for the total contract, depending on the resort. If you got it for $7,900, that's great. I wouldn't run out and start buying up contracts because they're $100 to $300 cheaper than they will be in a year.
2) As the economy settles down (and the buy out has not helped the economy in my opinion - if it did, the economy would have started to bounce back already instead of keep falling), Disney will not let these contracts through at these lower rates. You'll see the rates start to climb again. Keep in mind Disney will NEVER lower their sale prices. As the new resorts start to hit the market, you'll see the sale price just get higher and higher. This will help drive up the resale market as well.
3) Disney will offer contract extensions to the current owners of the rest of the resorts that expire in 2042. This will keep the cost of the resale up as well. It is in their best interest to keep offering these extensions. Most of what you pay for in any timeshare is marketing. Contract extensions and even add ons are a lot cheaper for Disney to market than going out and finding a new person to buy into DVC.
4) The price increases will be slow. Yes, people who purchased DVC in the '90's could sell it for possibly more than they paid for it, but that's a 10 year span. I purchased a resale in 2007. I don't expect the price will be high enough to make me want to sell it for at least 10 to 15 years.
Now, the only thing I'm really worried about with the DVC "investment" (and no, I don't think I'll ever make money on this, but I will end up saving money on my trips), is if Disney's level of service and reputation declines significantly. This could happen with a change in philosophy, staff training, or god forbid, Disney is purchased by another company (hello Comcast).
