The next photokina will take place in May 2020.

"Imaging industry and Koelnmesse
decide on new starting point for the new annual cycle.

Following a successful photokina 2018, the German Photo Industry Association
(PIV), as conceptual sponsor of the trade fair, and the event's organiser
Koelnmesse have agreed not to organise the next leading global trade fair in May
2019, as initially planned, but in May 2020. From Wednesday 27 May 2020 to
Saturday 30 May 2020, all the market leaders in the imaging industry are
expected once again in Cologne. The decision to postpone the start of the
announced annual cycle by one year is intended to give all participants the
opportunity to further develop the new concept for photokina and to tap into
new target groups among exhibitors and visitors in order to heighten the status
of the trade fair as a global platform for the photography and imaging industry."

As quoted from elsewhere, "Does it really matter that Photokina was cancelled? There's CP+ 2019 at the end of February. The Japanese camera makers can showcase new products at that show, which is probably more economical and logistically easier for them anyways."

I don't think no Photokina next year will be a problem really (hopefully).
