The BAHA5 was released by Cochlear about a year ago - which was when I upgraded. It's phenomenal. It replaced the BP100.
As Necromancer said, Cochlear recently released the BAHA5 Power and the BAHA5 Super Power. They are stronger models than the BAHA5, which is typically for those who have "normal" hearing in their "good" ear. The Power and the Super Power would be comparable to upgrades for the old Cochlear Intenso - generally worn by those who have diminished hearing in their "good" ear.
Your level of hearing determines which Cochlear BAHA would work best for you.
