The Verge have reported that people they know, know people at Samsung and those people at Samsung are delaying the release of the Samsung Galaxy S3. It was expected that Samsung would announce it at MWC in Barcelona at the end of February. But now it sounds like they will just be announcing other products, a Windows Phone or new tablets maybe. It seems that the delay is to do with the US market. As the Galaxy S2 was released quite a while after the UK in the US last year.
We will be at MWC, so no doubt we will cover whatever Samsung do decide to announce first hand.
