Galaxy S9 and S9+ launch date, according to rumor

According to a C-level executive at a major casemaker, the go-to-market schedule for Galaxy S9 / S9+ is as follows:
— Evan Blass (@evleaks) January 16, 2018
Launch - 2/26
Pre-orders - 3/1
Ships/releases - 3/16
So, the 26th of February is the day MWC starts. It's hardly a surprise Samsung would choose to announce the Galaxy S9 phones right then and there. Most manufacturers do that so that conference-goers will have the next few days at MWC to visit the Samsung booth and test out the new devices.
But wait a second — you may exclaim — the Galaxy S8 was released on the 21st of April, 2017. This means that the Galaxy S9 will be launched well before the 1st year of its predecessor is up. Well, yes, but that's technically because the Galaxy S8 was late, not because the S9 is early. See, back after the Note 7battery boom debacle, Samsung took some time to improve and secure its building processes, and deliberately pushed back the Galaxy S8's launch date. Now that these issues are — hopefully — behind us, the Galaxy S9 can put the Samsung flagship release schedule back on track.
So, this information sounds pretty plausible. Who's ready to throw some money at the new Edge screen, Infinity Display craziness from Sammy?
