Samsung to announce Galaxy S III today

The new Samsung Galaxy S III is set for launch in London at 11 a.m. PT/ 2 p.m. ET/ 7 p.m. UK time.
 It's the third generation of device in a popular series that started with the Samsung Galaxy S and the Samsung Galaxy S II.

Word has it that the new smartphone could have a quad-core processor and a large screen in the 4.7-inch to 4.8-inch range. Fans are also hoping the display will be Super AMOLED or even Super AMOLED Plus.

It's unclear whether Samsung will announce U.S. carriers today for the new phone at the event. If not, it's likely the company will talk about its U.S. debut next week at the CTIA trade show in New Orleans.
