i think the most surprising would be smashnova beating serena.
the others are more likely to happen. i.e schnyder is in good form and the last time we saw venus she didn't play great. but i still expect venus to win.
farina elia beating capriati may happen b/c jen had such a bad indoor season and may not feel confident but she did get a win in her last tounie. i expect capriati to win.
dementieva beating henin is probably the least surprising in terms of form, recent results and the level of play that both can reach. dementieva has has some good form this inidoor season but has run into trouble early in each tournie. henin has also played ok this indoor season. if dementieva contiues the good form i expect her to henin otherwise it is henin's match.
