This worries me as well. Like I've mentioned before the proportion of points we have resale is small, but due to banking of points from 2 previous use years to this one, we have slightly less than double our points for this year. *If* Wyndham decides that all of those banked points are VIP points (which we have more than enough in each use year to make that a reasonable expectation) and *If* Wyndham decides that all the points we have used to book current reservations are with VIP from this year, we still have left over VIP points along with our bucket of resale points. Our use year is better than yours since it just moved over in July and if Wyndham makes the assumptions I made then it should be ok, but if they go back to the two previous use years and try to determine which points we banked it's going to be a PITA.
On the other hand, if all the points being banked to the future go with the certain account they were banked from, I might finally have a case for using more than my yearly allowed points at outrigger properties since their argument had been that they had no idea what points I banked or where they came from, so no way you could use more than your yearly allotment. [yes I know this last one is wishful thinking and my head is fully submerged in the sands of denial}
