I expect ours will be written off too - no airbags went off, but it's damaged at least one panel and the bumper, as well as all the plastic parts behind them, and I think it's moved another panel as it doesn't look straight any more - even without that, the parts will be expensive, and putting them on and spraying it the right colour will in all likelihood spell the end for the car, which is a shame as it was clean, had a full service history, and I've spent a few hundred quid on replacing parts to keep it working perfectly in the past 12 months.
I'm just waiting for the almost inevitable game of 'we think your car is worth £book value -n' 'well I think it's worth 'cost of similar car in Autotrader +y' to begin.
