Utada's sickness definitely threw a wrench into the whole machine behind TITO. Early promotion is crucial to an album release and since TITO unfortunately couldn't enjoy such promotion, now IDJ is probably trying to figure out how to proceed. Releasing another single will be difficult because the album probably already has a 'flop' reputation to it and that'll just make it harder to find support at radio.

If I were to guess I'd say the next move we'll see from IDJ is to try to release the album in other markets-- Europe, to be more exact. If they find some success there, then they'll try to leverage that back in the US. That's just me speculating, though.
