This far out, those numbers are looking good for your chances of an op-up to be honest. Obviously, a lot can change but it's already only selling W only and that's despite the fact that the CW cabin is still selling I. You've got over two weeks for last-minute business trips to come along, but plenty of people have a WTP-only travel policy and W8 usually allows for plenty of overspill into a J cabin.... Admittedly there's not yet much pressure from economy to roll everyone forward but, given that status or paying passengers mean that there are currently only two aisle seats plus the bassinets (and the middle seats!) available, I'd be confident that some people at least will be upgraded.
While the flight itself is lightly loaded, WTP is shaping up to be very full indeed.
