"An insider suggests Samsung Galaxy S III will be powered by quad-core CPU and a shooter camera with 12 megapixels. Expect its release to hit on April after Mobile World Congress."

via Techspy: Samsung Galaxy S III Release Date and 12MP Specs Next Quarter

I wonder if its the same 'insider' that released the much anticipated iPhone 5 specs for Q4 2011

not sure i believe anything to there is an official announcement these days .....

Am sure Mark Langshaw (Digital Spy tech page) will again remind us the possible spec of the iPhone5 & Samsung s3 for the umpteenth time before release

Meanwhile the latest rumours are the Galaxy 3 WON'T be unveiled at MWC.

I don't understand the megapixel race, once you go beyond 5MP on a phone the difference is marginal, the images don't contain any more detail, just take up more pixels and more space.

Not a dig at Samsung, I'm sure many phones this year will be 12MP but it really tells you nothing at all about how good the images will be.

Read somewhere that the SG3 is just the SG2 with a better camera, same design, ok yeah you can get Quad but is that really essential, the SG2 is already lightening fast for a phone!

It's not a bad idea as it will save Samsung on R&D and most people who have an S2 will still be in contract and it's a massive upgrade from the S1.
