Not likely. Since they didn't announce the prices at the media event, they're probably not going to announce them until they actually go on sale in the stores and online.
I agree. Apple could have made BTO info available 2 weeks ago but chose not to, thus precipitating the annoyance we see on this forum. If they haven't listed the options and prices by now there is no reason to expect to see them until the sales pages are live and ready to take orders.
