Considering that Digitech just recently released a Whammy with a Drop Tune feature Morpheus gives a resounding answer.
The Morpheus Bomber.
Proprietary polyphonic pitch Shifter
Pitch up a 2nd, 5th, 1 octave or 2 full octaves
Pitch down a 2nd, 4th, 5th 1 octave or 2 full octaves
Features a 3 octave foot controlled Dive Bomb!

Looks like it's biggest gimmicks are the footswitch controls (much like on the Whammy II and Whammy/Wah), a USB port for updates, and it's polyphonic nature - hence, big chord whammy antics without that digital garble glitch you'd usually get from other pitch shifting units.
As a Whammy enthusist, I may have to try these out.
It certainly is cool looking.
