Just a few days we heard a pretty compelling rumor that the Galaxy S8 would be launching on April 21st to cap off a preorder period starting April 10th. While that rumor is still pretty plausible, another leak suggests that the launch date has been pushed back a week to April 28th.
The good news is that the delay won't affect the device announcement at the end of March, although it could push the preorder dates back a week, too.

There aren't any specific reasons for missing the original April date, but after the Note 7 it's very clear that Samsung is trying to nail every little detail about the Galaxy S8, and you can't really blame them.
That's still a month and a half out, but we'll keep you updated if anything else leaks or changes.
