I'm okay with Andrea returning as I think she's "playing the game" better than Holly did. Though I will miss Holly and her bikini-centric apparel. From a boob-lover's perspective, I wouldn't have a problem with Stephanie going to Limbo, but I do think she's a better player than competing team captain Mike; I would enjoy this show a bit more without him, so I hope he goes first.
Of the ladies, both Joy and Erica are coming off with positive and/or sympathetic edits from both the aired episodes and much of the live feed footage, so I hope they make it all the way to the end (and also because they're busty hotties).
ETA: Well the evening stream basically confirmed that Mike's going to Limbo, which makes me happy. Andrea's the only lady eligible to join him, but there was serious consideration among the others about voting someone else down there in anticipation of Mike's departure and to keep Andrea eligible for team captain-hood next week. These additional feeds (and the fact that the players don't seem to realize when they're on) have been very insightful!
