I'd say that Yau Man would be seen as a big strategic threat, along with Cirie, Fairplay and Jonathan. Fairplay and Jonathan were both unstable with their alliances. Ozzy will be seen as a physical threat, and since they only saw the first few episodes of China, when James dominated tribal challenges, James will be seen as a physical threat too. Ami said that the male survivors don't know anything about her except that she's a man-hater, so that could put a target on her. They never saw the second half of Amanda's game, which is when she began to make strategic moves and target her own alliance, so she won't have a target. Parvati won't have a target either, especially if her strategy is flirting. Eliza also seems too neutral to have an immediate target, but she may annoy her tribe.
