Star Wars Episode 7 will be quite different with previous series

Star Wars Episode 7, which would follow the events of 1983’s “Star Wars: Episode VI - Return of the Jedi” It will release in 2015(tha same as avatar). What we really care about is the plot on the upcoming movie, below is what I get from some movie posters.
It said that the Star Wars 7 will be quite different from the early series. It will not just starting with the old Twentieth Century Fox logo and song, Instead, the movie will start with the Disney logo and music. And the movie style will be very different comparing with previous series. So there will be so many new elements and possibilities in Star Wars Episode 7! It;s really a anticipated movie in 2015.
