Samsung will take over New York City's Radio City Music Hall on Thursday to unveil its new Galaxy S4 Android smartphone. But thanks to Samsung's marketing team and some leaked images, phone-watchers are starting to put some of the details together ahead of the big reveal.

Today Samsung has released the second teaser video for the phone and event. The video picks up where the last one left off - Jeremy Maxwell, a young boy, has the phone in his possession, but Samsung has told him he cannot show it to anyone or take it out of the box. Jeremy does say in the video that it's his "favorite color" and that its "unreal" and "beautiful." That's not all very revealing, but it does imply that the phone will come in a selection of colors. Currently, the Galaxy S 3 comes in a "pebble blue" and "marble white."

But beyond Samsung's controlled marketing, other details have started to emerge about the phone. Purported photos of the device have been posted on Chinese forums and discovered by posted by Sammyhub.com. In these photos, the Galaxy S4 appears to have a similar design to the Galaxy Note 2 and a high-resolution 1080p display.

Other rumors have said that the Galaxy S4 phone (Samsung often uses Roman numerals, as in Galaxy S IV) will have an improved camera and a quad-core processor. HTC's One, which was announced last month, will go head-to-head with Samsung's new phone. HTC's new phone has a 4.7-inch, 1080p screen and an aluminum design.

Samsung has said that many of the big features will be software-based, and The New York Times reported last week that the phone would have an "eye-scrolling" feature. Users will be able to look down and the phone will do the scrolling for you, the report said. Samsung's Galaxy S3 has a feature that uses the camera to make sure you are still looking at the phone. Called Smart Stay, the screen will turn off if it doesn't see you looking at it.

At the end of the teaser video, Jeremy starts getting ready for his "big day" by putting on some "power ties."

Something tells us that his big day is the big event on Thursday and that we will all be the first to see what is in his magical box. ABC News will be reporting live from the event, which begins at 6 p.m. ET.
