It all depends on the response to the EMIMs. Graz, the Apogee guy, spent a lot of time and effort engineering a technically superior replacement (they sound incredible, actually!) for the EMIM. If he can turn a profit, then he will move on to other drivers like EMITs, HE-EMIM, etc. If he ends up with a boatload of EMIM diaphragms nobody wants, he will not do any other drivers.
So buy up, folks!
