Samsung has issued invitations to a media event where it will unveil the much-anticipated Galaxy S III smartphone. Though rumors about the release date for the follow up to the popular Galaxy S II have been all over the board – sometimes in March, sometimes in April, it appears that the phone will actually be hitting store in May.

According to the invitation, Samsung will be unveiling the Galaxy S III at an event on May 3rd at the Earls Court Exhibition Centre in London, England. The event is scheduled to kick off at 7 PM local time (2 PM EST).

Little is known about the Galaxy S III, and the invitation reveals nothing. Though the rumor mill has suggested things like a 4.7-inch AMOLED HD display, a 1.5GHz quad-core processor, 32GB of memory, 1GB of RAM, and a microSD card slot. There have even been rumors that it would ship with a Liquipel waterproof coating.
