The official invitation does not reveal much other than a number nine and words: "The Camera. Reimagined", so it is safe to assume that the new camera will be a key part of the Galaxy S9 and Galaxy S9+ announcement.

Earlier leaks and rumors also suggested that the Galaxy S9 series will use Qualcomm's latest Snapdragon 845 SoC and Samsung's own Exynos 9810, depending on the version, have Infinity displays with even thinner bezels, rear-mounted fingerprint sensor, dual-camera setup for the Galaxy S9+ with high frame-rate videos and more.

According to the earlier Twitter leak from @evleaks, Galaxy S9 series should be up for pre-order on 1st of March with shipping scheduled for 16th of March.

According to a C-level executive at a major casemaker, the go-to-market schedule for Galaxy S9 / S9+ is as follows:

Launch - 2/26
Pre-orders - 3/1
Ships/releases - 3/16

There will be plenty to see at the Mobile World Congress 2018 which will kick off on February 26th and Samsung's Galaxy S9 and Galaxy S9+ will probably be stars of the show.
