flyhigh, 'soon' when compared to the life cycle of planet earth would be spot on, however in human terms, it's still a way off yet
Indeed they will all be gone in time (in much the same way as British Airways no longer flies the HS Trident), but for your info, the last A345 is 'currently' slated to leave at the end of 2017 with a slow reduction in 'classic' Airbus' between 2013 and then.
Hope this helps.
