I just read this from the tube's website on the ask tube section
"Question


When will the Tubes be returning to normal after the events of 7 July?






Answer


We will not be in a position to add to the current level of service on
the Metropolitan, Circle, District and Hammersmith & City lines for a
number of days.

The service on the Piccadilly line will remain suspended between Arnos
Grove and Hyde Park Corner for the foreseeable future.

Following agreement with the Police, the Victoria line is now stopping
at King's Cross/St Pancras. The Northern line will start stopping at
King's Cross/St Pancras again from Monday 17 July."


this text gives the ideia that the suspention is here to stay, what do
you think?
