Scribble Jam just announced their 2014 version. They will fund this through Kickstarter and they need to raise 100 000 $ to make tis happen. So they really need the support from fans. Scribble used to be the biggest Hiphop event in the USA and they stopped after 2007. And if they don't get the funds they need this time they won't try to organize this again. So this is really the last chance to make this happen. You can read more about it in the link.
