Just in case you don't know, GSM World is the largest worldwide tech show for phones. Alas companies like Apple don't do much there so you don't usually get major announcements like this there from Samsung either. But looks like they are taking an opportunity to do it now.
Likely it will ship 2-3 months later after the announcement.

"You won't see Samsung's upcoming flagship phone before CES 2018 ends, but you won't have to wait that long to get a peek, either. DJ Koh, the Korean conglomerate's mobile chief, has announced at a press conference in Las Vegas that the company will launch the Galaxy S9 and S9+ at the Mobile World Congress. Samsung will also reveal when the phone will be available for purchase at the annual trade show, which will take place at the end of February in Barcelona, Spain."
