not going to happen anytime soon 
anyways, EE chose the haken engine for what it is… its not going to change anytime soon.
Id say it’s much more likely, that EE, would deliver another synth, that’d just use the key technology but with a more ‘familiar’ synth engine… perhaps similar to the original Roli.
in the mid-term, one exciting area is what we know Haken are working on, which is a new ‘synthesis module’ for eagan matrix. (*) . they have been showing this off at Superbooth for last couple of years… but its hard to tame 
yes, there is talk of a new EM editor… but last time I spoke to them, it did NOT sound like it was close…and Id also be surprised, if from a users perspective its much different. ( ** )
as for EE, there are limits to what they could do in their firmware, they are pretty at the limit at what they can expose of the EM.
due to EMs nature, it’d not be easy to expose much more.
I know… perhaps sounds like Im being conservative, but rather I see it as realistic, given the size of the teams involved and resources they have.
ofc, they might be doing stuff, and keeping it quiet… but they also might not 
( * ) consider this a new ‘oscillator’ for the existing EM, EM is fundamentally unaltered.
( ** ) mostly this sounds like moving the EM away from Max/MSP for support reasons… though, I’ll say Haken themselves think Max has been very good for them, which is why they are not in a huge rush away from it.
Id not be surprised if the resulting application, looked pretty similar, but with just a few QoL changes…
id be amazed, if the matrix style was changed… as this is the design of the synth engine, its not just a ui representation.
(Ive reverse engineered most of the editor… so I know how it all ‘ticks’ !)
