Earlier this morning in Weeks, the only thing past February was a studio in May at OKW.
I would recommend placing an ongoing search. When deposits go in, they do not last very long. Unless you can obsessively check inventory, you might well miss a unit that you are hoping for. And, even then an ongoing search can only help. (But, still check yourself, just in case.)
As near as I can tell,
DVC seems to deposit most inventory in two "waves": one wave at 10-11 months prior to use, and another at 5-7 months prior to use. That's not entirely precise---the waves are "smooshed"---but it gives you an idea. So, right now, the first "wave" is late May to early June, and the second is late January to early February. If you are hoping to maximize your chances for Summer '11, the time to start your search is *right now*.
And, one final caution: in May of '09, trade power was recalculated globally, significantly tightening the ability to "trade up" in terms of supply/demand. Several "tiger traders" (deposits that could see anything in the spacebank) were declawed. So, unless you have *recent* experience for how this resort trades, it is possible you could be unpleasantly surprised. If you would *only* deposit to RCI to get a DVC unit, you might want to rethink your plan. If you would eventually deposit anyway, then you may as well roll the dice and see what happens.
