Our beloved Portuguese-speaking brethren at Gizmodo Brazil scored exclusive photos of what could be the Samsung Galaxy S III, which is due for a formal launch on May 3. If this is it, it does seems to be an incremental update rather than a major overhaul.

According to Gizmodo Brazil's source, the alleged-S III is thinner, yet heavier, with a 12 MP camera. Here's a look at its front and back sides:

Quite frankly, the photos leave something to be desired. (Taken with an iPad? For real?) And acording to Gizmodo Brazil the serial number (Samsung GT-I9300) matches up with what GSMArena said would be the Galaxy M. Having said that, their source is quite confident that this is the S III, and it does look pretty similar to the press shot that GSM Helpdesk Netherlands scored last month.

But what do you think. Is this it? [Gizmodo Brazil]
