Infected Mushroom released another plugin recently:

It's a pitch-tracking poly-Bode-shifter. The pitch tracking part 
is secret(tm).
The frequency shifting is regular, doesn't need Overlap Add like 
pitch-shifting.

The phase vocoders of IRCAM are very impressive at work, they 
have. I remember a demo where they changed male to female with 
algorithms tuned for a voice.
But it has different latency characteristics, overlapped FFT 
easily goes into the 20/30 ms.
