Samsung's Galaxy S 3 phone.

The Samsung Galaxy S4 or IV is coming, that much seems all but certain. But after a tweet from mobile-review.com's editor-in-chief Eldar Murtazin yesterday told us to watch for a "big announcement" on March 14, it seems we may now have a date.

Save the date for a big announcement - March 14 :) And keep silence ;) HTC will miss HTC One sales again :( Like it was in 2012.

Sources told The Verge March 14 is "definitely' the date, so it's now looking more and more like the we'll be feasting our eyes on the Galaxy S4, the update to Samsung's popular Galaxy S3 phone soon. The leak of a supposed March 14 release date happened yesterday, just one day prior to today's New York City HTC event where the new HTC One was unveiled.

Samsung has passed by the other Android phone makers in terms of market and mindshare. In Jan. Samsung reported that it had sold over 40 million Galaxy S 3 phones since launching the phone in May 2012. The phone, which has a 4.7-inch, HD Super AMOLED display and 8-megapixel camera, released on all four major U.S. carriers in June. According to the rumors, the next version of the phone will focus on software features rather than hardware.
