It looks like he is seriously considering a 'Serge Voltage Controlled Slope' -inspired A-100 module.
If there is enough positive feedback it will be manufactured with the license of the copyright owners of the Serge module ( and it may also have the additions that Ken stone has designed).
Because of the license fee, the module's price will be a bit higher than standard A-100 modules.

In time these merged into the classic Dual Universal Slope Generator.(Vimeo link with video)
For example;
The Serge VCS module, (re-)released in conjunction with bananalogue.com was/is an extremely versatile control voltage generator and audio source.
The Bananalogue VCS and CGS75 are both an adaptation of Serge's original circuit with a few new features.
At first glance it seems to be a VC slew limiter but after a closer look you can discover a very versatile module which can be used as a VC-LFO, VCO, AR-envelope, VCF, envelope follower, waveshaper, subharmonic and a trigger delay.
That's nine functions in one module!
It is not sure which functions the Doepfer module will have, but i guess they will try to get the most out of it.
So, the question in the Usergroup is:
" Would you buy a Doepfer A100 'Serge Voltage Controlled Slope' inspired module? "
The poll will remain open for one month, until 19th of December.

For those interested in the theory of operation, I recommend Tim Stinchcombe's page on this subject.
