The Galaxy S8 press shot shows the confirmed announcement date, along with a wallpaper that looks rather similar to that of the Galaxy Note 7. A Pearl Black color is also seen here (appearing similar to the newest Galaxy S7 edge color), not to mention the sleek form factor that Samsung teased earlier with the Galaxy S8 signup page and “Unbox Your Phone” mantra. 
A closer look at the Galaxy S8 (it's hard to tell if the 5.8-inch Galaxy S8 or the 6.2-inch Galaxy S8+ is shown here) shows the iris scanner/camera, along with the volume rocker on the left, the dedicated Bixby AI button, and the power/standby button on the right side. The little white screen “slither” you see on the phone's right near the power button teases the dual-edge functionality that yields the Edge Panels when swiped from right to left.
Apart from the iris scanner, Bixby button, and dual-edge design (along with the ultra-thin bezels), little else is seen here. This press release shot continues to drill home the point that Samsung will announce the next Galaxy on March 29th (presumably around 12:23PM, since that is the time listed on the device).
Alongside of the 5.8-inch and 6.2-inch curved Super AMOLED panels, 8MP front/12MP Dual Pixel back camera combo, octa-core Qualcomm Snapdragon 835/Exynos 8895 SoC, Samsung has said that it intends to bundle a pair of Harman AKG headphones into every Galaxy S8 box – which means that AKG audio is expanding beyond just the newly-announced Galaxy Tab S3.
Update: If you look at the bottom corners of the screen, you might notice that they're not perfectly curved. There's a chance of the image being a fake, so take it with a pinch of salt.
