I believe Obama, like Hillary, will make the point that his nomination is a historical first

Especially on the date of Martin Luther King, Jr's "I got a Dream" speech. Hillary did a damn good job about talking about the historical struggle of women and on Thursday I think Obama will have an equally good opportunity to speak about the historical struggle of African-Americans from slavery to the White House. It's going to be a meaningful speech, just like Sen. Clinton's.
