When I got mine I asked the ticket office the very same thing and she said it hadn't been confirmed yet but they expect to be told that there will be tickets for sale at the ground on the day for the away end. With this in mind, and the fact we have now probably sold the initial 2,500 hopefully we will take a good 3,000-3,500.
Cheers mate. Will give the ticket office a bell on Friday, to check.
