OK, so there are "get to know" videos with Jeff and each of the new houseguests and Elissa is EXACTLY like Rachel. I'll update this as I view the different houseguests.
Elissa: Rachel clone
Nick: Seems really annoying
Spencer: Long time BB fan, seems like a less annoying Adam. I see him trying too hard too early
Aaryn: Big BB fan, won't jeopardize her values and morals, surefire loser
Howard: Looks like a good mix of brains and brawn. His arms are huge and will make him an early target. I like him
Judd: His accent is going to kill me. He says he has a temper and he doesn't seem too bright. His time in the house won't last long
Andy: Has GOT to be the token gay. Lively personality, people person, very emotional. He will bring drama, but he's another surefire loser
David: Surfer guy, says "bro" or "dude" at least once every second. I hate him already. As a bonus, he doesn't like to shower, he is DOOMED
McCrae: Huge BB fan, watches the feeds. He's a pizza delivery boy......really? Seems like a decent guy, but doesn't bring anything unique
GinaMarie: Big personality, seems like a cool girl to have a beer with but might get annoying after a little bit. Brings that NY/NJ attitude
Candice: NOT what I was expecting. Former NFL cheerleader, seems kinda cool and laid back.
Amanda: She has bitch written all over her IMO. She will put up a nice front for a week or two, but she's going to piss people off
Kaitlin: New to the show...bartender...23...gee, I wonder why she was cast? She seems like she will cling to a bigger personality and ride along for a while, but she's not winning.
Jessie: Another mid 20's female with not much going on. She's really emotional, yeah, good luck with that
Helen: I'm not sure how she meshes with all the young kids on the show, but she appears smart and strong (emotionally). She's going to last a long time
Jeremy: All American guy, I think Jeremy is the guy American latches on to. He says he's a sucker for women, so he's a target to be used by someone in a small bikini.
