I could honestly see one of the next couple 'singles' they put out after Timebomb being a brand new song. Also a new record maybe late summer/fall 2012? Maybe the entire album with just one producer could really do the trick.
I doubt they will have an album out in 2012. Dirty Work took an extra 6 months longer than they originally said. Plus, I think Time Bomb will actually be a hit for them and they will do a little more behind this album before moving on.
But i agree with you that Timebomb will probably blow up and do for them what they have been striving for for awhile now
