Aprilia have until 3rd May to cough up some cash to cover debts, but I'm sure they will meet this one way or another.
They may well do the same as Moto Guzzi by stopping production of bikes and clearing out the stock they have sitting there (probably at bargain prices to importers) and release a whole chunk of cash.
Things should then pick up again, but spares might take a while to come through.
