I am seeing a dramatic drop in links reported in WMT too.
I also note a drop in links, but not in sites (e.g. one site that was showing 60+ links is now showing 23, but all except the disavowed site are still there). Not counting the disavowed links (192 from one site, all to my Home page, all with the same anchor-text, so quite possibly a linking issue for Penguin) the overall drop is around 30%.
I think in my case it is an improvement: a lot of the sites showing mulitple links are not spidered by Google at all frequently (the one I disavowed was reporting 90 days since last crawl), and I think a lot of the links showing in WMT are either dynamic pages or get removed/renamed much more often than Google's crawl rate. Most of these are also worth little, if anything, in terms of SEO/PR (they are at best PR1), so losing them is of no real concern to me.
