Anybody know when the Victoria Line weekend suspensions will end?

This is the most detail I could find on the TfL site:

Our Victoria line upgrade will deliver new trains, track and signals, which means faster, smoother and more reliable journeys.

By 2012, 47 new trains will be in service, each with more seats, higher ceilings, wider aisles and doors, plus improved ventilation and lighting, and an energy-efficient braking system.

Safety features will include digital CCTV cameras and push-button emergency alarms connecting directly with the driver. There will be improved on-train passenger information available, and carriages will be easier to access.

Already more than three-quarters of the track has been renewed and two-thirds of the new signalling equipment has been installed. This means we will be able to run more trains closer together safely - vital during busy periods.

OMG so this goes on until 2012! Help.
