Within 12 months? It's almost certain that will happen, though I've absolutely no clue when in those 12 months. The last few years they have updated them in March/April and then again in September/October, but people are claiming that won't happen this year and they won't be updated until early next year. I think it's almost certain they will have been updated by June next year though. My advice would be get one now, I doubt they'll ditch the unibody design any time soon.
