But is there enough turnover to make this a viable, primary source of revenue? (See my conspiracy post on the "early deposits" thread. Marriott had a "single channel" conversion to dump their bad weeks ... Starwood messed up this opportunity by creating "two channels). Makes it much trickier!

).
It's enough for now. Starwood is not intent on growing top line timeshare sales revenue. They have so stated. But, it does account for why they are being very aggressive with ROFR. They are not just sniping the very low resales. But,are in fact pushing prices up. They DO need the inventory to maintain its flat top line revenue target. It also supports my rather ambitious thinking of how much Starwood may be willing to pay to exercise ROFR at some point in the future. 40% of the retail sale price approximates what it costs to build, without having to risk the capital associated with building.
(ROFR enables them to modulate its inventory investment closely with sales productivity. Or, shut it down if necessary).
Of course, this can change if the economic climate improves dramatically. But, they are more likely to take an asset-lite approach if it does. This means partnerships with other systems, or, expanding ops management of small/independent systems. Starwood has indicated a lukewarm interest in this approach, but only if it is compatible with their standards.
RE: your conspiracy theory, I think you are reaching too far.
Here is what I think:
Precisely because Starwood is no longer building, and is almost sold out of everything it has built, it must seed I.I. with inventory from somewhere. Unlike the Marriott legacy system, Starwood controls the flow to I.I. for everything.
The I.I. affiliation agreement possibly contains a minimum inventory mix for each resort that cannot be met with standing unsold inventory. So, Starwood is using its predictive model to cut inventory loose. I would think doing so early enables them to manage SVN with more predictability.
