With Glee's execs meeting soon to figure out how to deal with Cory Monteith's (Finn Hudson) death, they will most likely be talking more about these new faces we'll see around McKinley High and New York City.
One of the new roles, confirmed by both outlets, is an African-American student at McKinley High, whom TV Line says will be named Ruby and E! News says will need to be able to sing. Could this be the replacement for Brittany (Heather Morris) so the New Directions will have enough people to compete? Most likely.
As for the other character? There is a bit of a discrepancy about her name, with TV Line calling her Julie and E! News referring to a Jenny, but both outlets are saying she will be a "cute and quirky" twenty-something, with E! saying she'll need to know how to sing. The name could be different because, since it's pre-production, sometimes names get shifted around, but we'll see!
Only TV Line is reporting about a third new character, Ryan, who they say needs to be able to sing and play guitar.
