The Musikmesse will now happen concurrently with the same dates as the Frankfurt Book Fair (October 22-24), which is a
huge trade show. The emphasis will be moving more toward a consumer-oriented event, which I assume hopes to draw on the number of people coming to the book fair. There's some
preliminary info online, but it seems more about marketing-speaking ("leveraging a synergistic collection of eyeballs for a 360 degree pivot where the rubber meets the road, while engaging in a snackable experience with enhanced, low-hanging fruit consistent with the organizations forward-thinking goals"). Okay, it doesn't really say that, but I assume more specifics will be forthcoming.
The trade show schedule for October looks pretty intense, anyway...
October 11-13 AES Las Vegas
October 13-16 Music China Shanghai - 20th Anniversary
October 22-24 Messe Frankfurt
October 28-31 Synthplex Los Angeles
