A blog that I read (diamond geezer) had a posting today where tfl's business plan was published last week was mentioned.

It no longer contains the Metropolitan line extension to Watford Junction.
The only listed projects are the Bakerloo line extension to Lewisham, the Northern line extension to Battersea and the London Overground extension to Barking Riverside.
Has the Metropolitan line project been quietly dropped?
