I don't remember hearing *any* rumors... so 'very soon' may well mean 'we announce it soon and will be able to deliver them... some time not so soon".
After V-Moda's seemingly good experience with developing the later part of the model in the open, i.e. taking in suggestions and opinions before finishing the spec, I'd be surprised if a successor to the M-100, their first model that (more or less involuntarily ;-) followed that procedure would be developed in complete silence. Though that is complete speculation on my part. What I do know is that a new in-ear is in development and about to be officially announced (or was it already -- don't know as I'm not into in-ears).
