We are hearing rumors that the much-awaited Samsung flagship, Galaxy S III may not be revealed at the MWC. The sources from where the rumors have erupted seem to be concrete and the rumors suggest the company had originally planned to announce its 2012 flagship Galaxy S III phone at Mobile World Congress in Barcelona late next month — has now decided to delay the news. 

The reason for the delay in announcement is said to be US availability, Samsung does not want a long lag between the global launch and US availability since US is a key market

We don’t really when the device will be announced but according to sources, it will be out in the market “before summer”. We should take the rumor with a pinch of salt since Galaxy S II was launched last year at the MWC but even if its shown off here, we’re sure Samsung would’ve planned some interesting devices for the biggest mobile trade show.
