Yes, but the Insignia, on which the Aura is based, was nearing the end of it's product cycle when the Aura was launched, so, now since the Insignia is being replaced, it's only logical that the Aura will be replaced now too.
IIRC it's a similar situation with the Astra...., I believe it's almost time for a redesign of it, and if so, we'll see a brand new Astra in a few years.
