It doesn't take much to get the Eminem rumor mill churning, and the rapper did just that on Tuesday (Mar. 30) with a mysterious post on his Twitter account. "Some big news is coming. Soon." read the simple message.

Eminem's tweet has re-ignited speculation about "Relapse 2," the follow-up to the Detroit MC's comeback album "Relapse" and one of the most anticipated releases of 2010. Initially slated for release by the end of 2009, "Relapse 2" was postponed after Eminem's studio sessions led to a shift in creative direction.

"I got back in with [Dr.] Dre and then a few more producers, including Just Blaze, and went in a completely different direction which made me start from scratch," Eminem explained at the time. "The new tracks started to sound very different than the tracks I originally intended to be on 'Relapse 2,' but I still want the other stuff to be heard." "Relapse: Refill," a reissue with bonus material, was subsequently released in December. Together with "Relapse," it has sold 1,891,000 copies, according to Nielsen SoundScan.

In an interview with AOL's the BoomBox two weeks ago, Just Blaze indicated that "Relapse 2" was near completion, saying, "I'm out in Detroit and we're wrapping that ['Relapse 2'] up now." Other leaked tidbits about the album came last year courtesy of Em's friend and producer the Alchemist, who told AllHipHop.com that the album sounds like "the most psychotic s---s I've ever heard," and DJ Whoo Kid, a member of Eminem's D-12 crew, who told MTV that "the crazy, lyrical, maniacal Eminem is back. Maniac!"
