we'll probably see her at WTF and davis cup final possibly
I'm not so sure about that because she's bound to be a target for a media and she doesn't like taking the attention away from Andy, who has yet to decide whether he's going to be at the O2 or not anyway. Also I've no idea where Ghent is but assuming a flight is involved then she might not be able to travel anyway because of airline rules.
You can see it on the pic of the shoes which is on another thread. I couldn't pick it up either during the match possibly because the design of the shoes makes it more difficult to spot.
