This sucks. This is also a very active discussion going on in the DVC subforum about whether to dump into RCI, or wait for some sort of announcement from DVC. What owners didn't want to do was dump into RCI and Disney comes back and says "hey here's something for you..." which would have been a better option than RCI.
I have banked 2018 points combined with current 2019 points for one night in May (24pts total) on an August UY, as disappointed as I will be to lose them...it could have been worse.
The joys of ownership have to be balanced with the risks and responsibilities of ownership, unfortunately. Even if I have to move out of my house, I still owe property taxes =( I ache for those with 100..200...300+ points at risk. That's potentially years of scrimping/saving for the dream vacation suddenly gone.
I have seen the thread on the DVC boards you refer to. I figure I will probably lose somewhere around 70-80 points (I need to look more closely), but I will be banking over 300 too (if I cancel Sept), so I will have a lot of points for next year. I feel bad for people losing a lot more than me. At least I have some time still before I have to decide what to do with July and September banking deadlines.
