Resale - NO points and NO trades within Marriott

I got out of a presentation last week and found out some interesting news. Within the next couple of years Marriott is scheduled to be out of Interval International. In addition to not allowing a 'secondary market' unit to trade in for points you will not be able to trade your unit within the Marriott system. The units will have to be banked with Interval. Only Marriott owners will be able to trade directly into Marriott Vacation Clubs. The only other way to get a Marriot unit would be if a secondary market purchaser banks it with Interval and you happen to find it. One good thing out of this is that Marriott will 'value' your unit based on location, rooms, ocean front/view etc when you want to trade. As you know Interval doesn't always take your deposit into consideration when giving you options for exchanges. Is it worth it? I still can't decide.
