I think the date needs to remain what it is. We need to see what the market is doing without inflated figures.
Your point is taken and Mr. Chase also makes the point of essentially manipulating home sales data. I guess it's a wait and see in hindsight kind of thing.
Could this be an attempt to keep house sales showing up over a longer period of time so the bad news of less sales after 5-1-2010 does not show up so quickly?
