I just got this from a source:
Sony will have a small press conference during the World Photography Awards. It is not of large scale, so the most optimistic expectation would be a lens announcement, definitely not a new body of any kind.
In the past Sony has announced some stuff at the World Photography Awards but I guess this time we probably will not get any product announcement.
At this point I think that if we are going to see something new this might be the new 24mm f/1.4 FE GM lens. And if there is nothing I bet we are going to get something new in May already anyway.
