I wrote Akai on this behalf one month ago. The International Software E-Commerce Manager and Lead Technical support replied independently, that VIP is there flagship software and in development still. Also the new road keyboard will be supported.
1. Watching the latest releases of InMusic, let me guess that the direction of the company is touch. To make this happen the whole ux of VIP must be rewritten and designed, which takes effort and time.
2. Akai advance production and other keyboard series has been stopped, to sell out "old" devices.
3. Akai released the Force controller, which needs its space for marketing and resources for software development /hotfixes.
= Combining these three guesses leads to my conclusion that there might happen something in q2/q3 or Namm 2020
