There's thread on namepros which is regularly updated with dropping LLL.in domains.
One thing though which has become very apparent over the last few months is that fewer and fewer all-premium LLL's are dropping. So far in 2010 I believe there's only been 2 or 3.
This is maybe not surprising since most owners are either end-users who're already making use of their LLL's for their websites, or domainers/investors who're now fully aware of their value. Neither of whom are likely to let these names drop.
I think this will very much be the case from now on, and eventually the same will be said for semi-premium and non-premium LLL.in's also.
