All signs point to a new No. 1 album at the top of the Billboard 200 chart next week, as we await the arrival of Green Day's "21st Century Breakdown."

The Reprise/Warner Bros. set will see an off-cycle release on Friday, May 15. (Most albums are released on Tuesdays.) Even though "Breakdown" will only have three days of sales on next week's Billboard 200 chart, it's likely it'll debut at No. 1. Sources say the set shipped over 650,000 to retailers — though it's not expected to blow through that quantity in three days.

The album will perhaps move what Green Day's last album, 2004's "American Idiot," did when it arrived atop the list with a career-best opening of 267,000. Of course, "Idiot" did so with a regular-length debut week, as opposed to the new set's abbreviated start.

No other new releases, nor holdovers on the chart, pose a threat to "Breakdown's" chart dominance next week.

Other new albums looking for a high debut include Cam'Ron's "Crime Pays" (Diplomatic Man/Asylum), Paul Wall's "Fast Life" (SwishaHouse/Asylum) and Aiden's "Knives" (Victory).

Nielsen SoundScan's sales tracking week, as reflected in the official Billboard 200 chart, runs from Monday through Sunday of each week. The newest Billboard 200 chart, released today (May 13) -- where Chrisette Michele's "Epiphany" (Def Jam) bowed at No. 1 with 83,000 -- reflected the week that ended on Sunday, May 10.
