So the latest is that;
1) The case may not proceed due to some pesky paper work. http://torrentfreak.com/megaupload-trial-may-never-happen-judge-says-120420/
2) Kim is mad, no kidding http://torrentfreak.com/kim-dotcom-lashes-out-against-corrupt-us-government-120420/
Ok 2 was funny but seriously they are continuing to investigate (from his side) the possibility of corrupt activities leading to the raid.
Also some other information that is related.
