There have already been plenty of leaks, but Samsung hasn’t yet formally announced its Galaxy S10 smartphone lineup, which is set to be offered in several different models and sizes. Even so, that's not stopping the company from kicking off S10 reservations ahead of next week’s Unpacked event.

Samsung has launched a website with details, and it’s promising customers up to $550 off the S10 with a trade-in of an eligible device. Devices will “ship by March 8th,” which is our best evidence yet of an official S10 release date (or time frame, at least). Placing a reservation will give you priority during a 72-hour window after preorders go live, but Samsung notes that “not all Galaxy device versions are eligible for this offer.” If you don’t preorder in time, you’ll lose your place in line.
