Ali Raisman and Gabby Douglas were both present this year again (like last year) -- they were on the 2012 Olympic team in London. Both girls are shown in the photo below, where the girls are lining up to present themselves to the judges before competing on the balance beam:

There were also a number of "throwback" people present that were really fun to see!
Marta Karolyi is the national team coordinator (and in charge of choosing the US Olympic team) -- this will be her last year, as she plans to retire after the 2016 Summer Olympics:
Above -- Marta is talking to Ragan Smith -- a newcomer to the senior level this year and doing really, really well! Look up a video of her floor routine -- it's adorable and the choreography is awesome.
Kim Zmeskal is coaching and has a couple girls from her gym that are on the U.S. national team. She was part of the 1992 Olympic team and also World Champion! (This is her below, center... looking over her shoulder.)
Shannon Miller's coach, Steve Nunno is back and coaching a girl who is new to the national team: Emily Gaskins.
