I don't think they will, but it might take months to get the money back and I see them trying to sell tickets for next year without having resolved repayment for this year...indeed the FAQ they sent out basically implied that
Hard to call this year, as city tend to see how one season ends before setting the prices for next. They are not quick at making decisions, and if there is the remotest possibility we could win the Champions League, they will want this to play out as it could mean they get away with another hike (in theory).
It would be a gesture of goodwill to set prices at 80% of last seasons if we get 38 games, and refunds fro this season if not played. City are still selling tickets for this season, only £63 South Stand for Norwich - I think the days of these prices are over for a while.
